Royal Way supplies oilfield sealing products including O-rings, Hammer Union Seals, swivel joint repair kits, wireline and setting-tool redress kits, packer elements, frac pump plungers, and custom rubber or composite sealing components. Availability is confirmed against the exact part reference or drawing.
Royal Way supports oilfield equipment and service applications, including flowline, valve, pump and downhole equipment. Product selection starts with the equipment model, service conditions and drawing.
Yes. Royal Way operates an ISO 9001-certified quality management system. The applicable certificate and scope can be provided during supplier qualification.
Yes. Send a drawing or sample, dimensions, required material or service media, pressure, temperature and quantity. Feasibility, tooling and inspection requirements are confirmed in the quotation.
NBR is commonly used where oil resistance and general service are required. HNBR can offer improved heat and chemical resistance in suitable formulations. FKM is often considered for higher temperatures or more demanding chemicals. Performance depends on the exact compound, not only the polymer family.
RGD resistance must be verified for the exact compound and service. Provide the gas composition, pressure, temperature, decompression rate, required test method and acceptance criteria before selecting a material.
Oil, 320°F and H2S do not identify a safe material by themselves. Provide the fluid composition, pressure, exposure time, decompression conditions, equipment design and required standard so a specific compound can be evaluated.
Royal Way does not claim API certification. When an order references an API requirement, send the standard, edition, product scope, drawing and acceptance criteria so the requirement can be reviewed and documented for the quoted product.
A packer element is the elastomeric sealing component in a downhole packer. When the tool is set, the element deforms against the casing or bore to help isolate an annular zone. Its geometry and material must match the packer design and service conditions.
An annular BOP closes an elastomeric element around different tubular shapes or an open bore within its design limits. A ram BOP uses opposing rams selected for a defined function, such as pipe, blind or shear service. Selection and operation must follow the equipment manufacturer’s documentation.
An S-Seal is a shaped sealing profile used in some wellhead and hanger assemblies. The profile, energizer, dimensions and materials vary by equipment design, so the drawing or part reference is required for identification.
A swellable packer uses an elastomer formulated to increase in volume when exposed to a specified fluid. The fluid, temperature, exposure time, well geometry and required expansion must be defined before selecting the element.
Rubber-to-metal bonding can combine sealing, support and location features in one component. Bond design, metal preparation, elastomer selection and inspection requirements must be matched to the load, movement, fluid and temperature.
Temperature changes stiffness, compression set, chemical resistance and service life. Published polymer-family ranges are only a starting point; use data for the exact compound together with the fluid, pressure, movement and exposure time.
MWD and LWD tools use several seal types to protect internal components during drilling. The correct seal depends on the tool model, groove, movement, drilling fluid, pressure, temperature and decompression conditions.
Provide the setting-tool manufacturer, model, size, current kit or part number, drawing or component list, and service requirements. Kit contents and material options should be confirmed for that exact tool before ordering.
Provide the swivel joint manufacturer, style, nominal size, current kit or part number, component list or drawing, and service fluid. Kit contents, seal materials and hardware must be matched to that exact assembly.
A lip seal uses flexible sealing lips and may be pressure energized. An O-ring-style union seal relies mainly on controlled squeeze in its groove. The exact profile must match the union figure and groove; do not substitute one style based on nominal diameter alone.
The seal is compressed in the union groove when the connection is assembled. Depending on the profile, line pressure may further energize the sealing lips. Reliable sealing also depends on the correct union, groove condition, assembly and service limits.
Hammer Union Seals are replaceable sealing components fitted between the union halves of flowline connections. The correct part is defined by the equipment manufacturer, figure, nominal size, seal profile, material and service conditions.
“Weco compatible” should identify an intended fit with a specified Weco-style reference. It is not proof of universal interchangeability. Confirm the manufacturer, figure, size, seal profile and drawing or part number before ordering.
Common field references include Fig 100, 200, 206, 400, 602, 1002, 1502 and 2202. A figure number may not fully define the seal, so include the equipment manufacturer, nominal size, profile and part reference.
Do not assume a used seal is serviceable. Inspect it and follow the equipment maintenance instructions. Replace a seal that is cut, deformed, swollen, hardened or otherwise outside the applicable acceptance criteria.
The ring supports the elastomer near a clearance gap and helps limit extrusion. Its geometry and material are part of the seal design and must match the union figure, groove and service environment.
Fig 1502 and Fig 2202 refer to different union designs and service classes. Components must not be interchanged because the nominal size looks similar. Confirm the manufacturer, figure, drawing and service requirements.
There is no single material for every Hammer Union Seal. NBR, HNBR, FKM and other compounds may be considered based on the fluid, temperature, pressure, decompression conditions, seal profile and equipment requirements.
A seal for H2S-containing service must use a specific compound and hardware configuration selected for the fluid composition, pressure, temperature, decompression conditions and applicable standard. HNBR or FKM family names alone do not establish suitability.
Color is a supplier identification aid, not material certification. Check the package label, compound code and supporting documentation. Do not use green color alone to identify HNBR or approve a seal for sour service.
FKM may be considered for certain higher-temperature or chemically demanding services. Compatibility varies by compound grade and fluid formulation, so review the exact media, temperature, pressure, movement and exposure time before selection.
HNBR can provide different heat, mechanical and chemical resistance from NBR in suitable formulations. It is not automatically the better choice for every service. Compare exact compound data against the application requirements.
Brass and stainless steel differ in strength, corrosion behavior, galling behavior and compatibility with the surrounding hardware. Select the ring from the equipment drawing and service requirements rather than by appearance alone.
Do not select an elastomer for acidizing from the polymer name alone. Provide the acid type and concentration, additives, temperature, pressure, exposure time and full fluid sequence, then check compatibility data for the exact compound.
PTFE may be used in certain sealing or backup-ring designs. Send the union figure, size, profile, drawing or part number and service requirements. Availability and construction are confirmed in the quotation.
The pressure rating belongs to the complete union assembly, not to the seal by itself. Verify the equipment manufacturer’s rating and the exact Fig 1502 configuration, then match the seal profile, material and acceptance requirements to that assembly.
NBR does not have one universal service range. The usable range depends on the compound, fluid, pressure, movement and exposure time. Ask for data for the exact quoted compound and application.
FKM compounds do not share one universal service range. The usable range depends on the grade, fluid, pressure, movement and exposure time. Ask for data for the exact quoted compound and application.
Hardness is selected for the seal profile, clearance, pressure, movement and material. Provide the drawing or original part reference; the quoted hardness and tolerance should be stated for that specific component.
Suitability for vacuum or suction service depends on the seal profile, groove, pressure direction, fluid and equipment design. Send the union figure or drawing and the operating conditions for confirmation.
Sizes are handled by equipment figure, nominal size, seal profile and part reference. Send the equipment marking or drawing and required quantity so current availability can be confirmed.
Sour-service suitability cannot be determined from an elastomer family name. Confirm the exact compound, product, fluid composition, temperature, pressure, decompression conditions, and the applicable edition and acceptance criteria of NACE MR0175 or ISO 15156.
Gas can diffuse into an elastomer under pressure. If pressure falls too quickly, the trapped gas may expand faster than it can escape, causing internal cracking or blistering. Resistance depends on the exact compound, seal geometry and decompression cycle.
Follow the equipment manufacturer’s instructions and isolate all pressure first. Verify the part and orientation, clean and inspect the groove, remove sharp edges or damage, and use only a lubricant compatible with the seal and service fluid.
Many pressure-energized lip seals face the open lip toward the pressure, but this is not universal. Use the equipment drawing or installation instruction for the exact seal before assembly.
No. Nominal size, figure and profile are part-specific. Use the seal identified for the exact union and confirm the drawing or part reference before installation.
A backup ring supports the elastomer at a clearance gap and helps control extrusion. Its material, thickness, split or solid construction and installation direction must match the seal and equipment design.
It depends on the component and equipment. Some seals can be fitted by hand, while others require sizing, insertion or protection tools. Follow the equipment instructions and avoid sharp tools that could cut the sealing surface.
Keep seals in their original sealed packaging in a cool, dry and dark area away from ozone sources, heat, sunlight, deformation and contamination. Shelf life depends on the elastomer, packaging, manufacture date and applicable storage standard.
Use lubricant only when the equipment instructions allow it and the lubricant is compatible with the exact elastomer and service fluid. Do not assume that a general-purpose grease is suitable for every seal.
Do not use a seal to compensate for a damaged sealing surface. Inspect the union against the equipment acceptance criteria and repair or replace the hardware when required before installing a new seal.
Possible causes include the wrong part or material, excessive clearance, damaged hardware, assembly damage, pressure outside the equipment limit or rapid decompression. Stop using the assembly and review the failed seal, groove, service history and equipment data.
Hardening can result from heat, chemical exposure, oxidation, ozone or age. Preserve the failed part and provide the compound reference, fluid, temperature, service time and storage history before selecting a replacement.
Swelling or softening often indicates fluid absorption or chemical incompatibility. Check the complete fluid formulation, temperature and exposure time against data for the exact compound.
A nibbled edge often points to extrusion into a clearance gap, but assembly damage or worn hardware can look similar. Review the groove, clearance, backup ring, pressure history and failed part before changing materials.
Corrosion can relate to the actual ring alloy, service fluid, moisture, dissimilar metals, storage or cleaning chemicals. Remove the component from service and verify the material and environment before choosing a replacement.
Low-pressure leakage can come from the wrong size or profile, damaged sealing surfaces, contamination, poor assembly, insufficient squeeze or compression set. Depressurize the equipment and inspect the full connection before replacing the seal.
Low temperature can reduce elastomer flexibility and make installation damage more likely. Check the actual minimum temperature, fluid, pressure cycle, compound data, storage and installation procedure before selecting a replacement.
Check the equipment manufacturer, figure, nominal size, seal profile, dimensions, compound identification, service conditions and required documentation. A supplier should confirm the quoted part against that information rather than relying on a generic compatibility statement.
Compare the drawing or part match, compound traceability, inspection documents, packaging, lead time and technical response. Do not assume OEM equivalence from a marketing description; confirm the exact acceptance requirements in the quotation.
Stock changes by figure, size, profile and material. Send the exact part reference and quantity for a current availability and lead-time confirmation.
Send a drawing or sample, dimensions and tolerances, material or service media, temperature, pressure, movement, quantity and required inspection documents. Feasibility and tooling are then confirmed for the quotation.
Lead time is confirmed after the exact part, quantity, material, tooling, inspection documents and packaging are defined. Include the required delivery date with the inquiry.
Availability depends on the exact equipment and seal reference. Send the manufacturer, model or figure, nominal size, drawing or part number and service conditions for identification.
Inspection and testing depend on the product and order requirements. Dimensional checks, hardness verification, material documentation or other agreed tests can be defined in the quotation with their acceptance criteria.
Samples can be discussed after the exact part and evaluation purpose are identified. Availability, quantity, cost and any test requirements are confirmed before shipment.
Royal Way accepts international inquiries. Shipping method, Incoterms, destination requirements and export documents are confirmed for each quotation and order.
Send the part number or drawing, equipment reference, size, material or service conditions, quantity and required documentation. Royal Way will confirm the identified item, quotation scope, lead time and shipping terms.
