High-Temp FKM (Viton®) O-Rings for Chemical Processing

For the most punishing thermal environments in the Oil & Gas sector, standard elastomers simply disintegrate. Our Ultra-High Temperature FFKM (Perfluoroelastomer) O-Rings are engineered to survive where FKM and HNBR fail. Capable of continuous operation at 600°F (316°C) with peak excursions to 620°F (327°C), these seals provide the ultimate thermal stability for High-Temperature High-Pressure (HTHP) wells, steam injection, and heavy oil thermal recovery. They represent the highest tier of sealing technology, ensuring equipment integrity when “failure is not an option.”

Technical Specifications

  • Pressure Rating: 5,000+ PSI (With Backup Rings)
  • Temperature Range: -10°F to +400°F (-23°C to +204°C)
  • Material: FKM (Viton®)

Applications

  • Downhole Tools, Used in MWD/LWD tools, packers, and bridge plugs where temperatures exceed 300°F and chemical resistance to drilling muds is required.
  • Chemical Injection, Seals for pumps and valves injecting corrosion inhibitors, methanol, or biocides (Requires Viton® GF).
  • Subsea Equipment, Christmas trees, manifolds, and risers requiring long service life and cold resistance (Requires Viton® GLT).
  • Gas Processing & Transmission, Compressors, dehydration units, and gas valves handling high-pressure gas, requiring RGD/AED resistance.
  • Refineries, Mechanical seals, flange gaskets, and heat exchanger gaskets handling hot crude oil, fuels, and hydrocarbon solvents.
  • Wellhead Control, Hydraulic control panels and actuator seals.

Kalrez® Equivalent FFKM O-Rings for Critical Valve Sealing

Executive Summary

For critical valve applications where seal failure leads to catastrophic shutdowns or safety hazards, performance cannot be compromised—but costs can be managed. Our Kalrez® Equivalent FFKM O-Rings provide the same high-performance benchmarks as industry-leading brands (like Kalrez® 4079, 6375, or 7075) but with significantly shorter lead times and optimized pricing. Designed for critical isolation valves, control valves, and safety shutdown systems, these seals ensure bubble-tight shutoff in the harshest Oil & Gas conditions.

Why Choose an “Equivalent”?

1. Performance Parity

Our FFKM compounds are formulated to match the physical and chemical properties of major brands.

  • Matched Modulus: Ensuring the same sealing force and feel.

  • Matched Resistance: Equivalent chemical inertness and thermal stability.

  • The Benefit: You get the reliability you need without the “Brand Name” premium or the 12-week lead times.

2. Optimized for Valves

Valve sealing requires specific characteristics:

  • Low Friction: For control valve stems (reducing hysteresis).

  • Explosive Decompression Resistance: For high-pressure gas valves.

  • Extrusion Resistance: 90 Durometer options for high-pressure seat seals.

Critical Valve Applications

Control Valves

  • Stem Packing: Reducing fugitive emissions (Low E) in varying temperature ranges.

  • Seat Seals: Ensuring Class VI shutoff in severe service conditions.

Isolation & Safety Valves

  • Emergency Shutdown Valves (ESDV): Seals that must work instantly after sitting static for months.

  • Subsea Ball Valves: High-reliability seals where replacement costs millions.
