FPM O-Ring 34.5x3.5 - FKM or Viton

Material Characteristics and Performance

The FPM O-Ring 34.5x3.5 (also known as FKM or Viton) is a high-performance industrial sealing ring designed for demanding applications involving elevated temperatures and chemically aggressive environments. FPM elastomers offer exceptional resistance to fuels, synthetic oils, lubricants, solvents, and process chemicals, ensuring stable sealing performance where standard rubber materials such as NBR or EPDM are not sufficient.
With excellent compression set resistance, dimensional stability, and mechanical durability, this O-ring provides reliable static sealing in applications where long service life and system reliability are critical. Typical operating temperature range extends from approximately -20°C to +200°C, enabling effective performance in high-heat and chemically intensive operating conditions.

Applications in Industrial, Hydraulic, and Chemical Systems

The FPM O-Ring 34.5x3.5 is suitable for sealing components in:
• Hydraulic and pneumatic systems
• Fuel delivery and injection systems
• Chemical processing and dosing equipment
• Vacuum and high-temperature service units
• Pumps, valves, compressors, and actuator housings

Its low gas permeability and resistance to aggressive fluids make it particularly suitable for chemical plants, refinery systems, laboratory installations, engine components, and industrial maintenance environments requiring durable, chemically stable static seals.

FAQ

Is FPM suitable for contact with fuels and synthetic oils?
Yes. FPM is one of the most fuel-resistant elastomers and performs reliably in systems containing gasoline, diesel, and synthetic lubricants.

Can this O-ring be used in high-temperature environments?
Yes. The typical operating range is approximately -20°C to +200°C, depending on system pressure and medium.

Is the O-ring suitable for dynamic sealing?
FPM can be used in limited dynamic applications, but it is primarily recommended for static sealing where long-term compression resistance is essential.

Does FPM resist ozone and weathering?
Yes. FPM is resistant to aging, ozone, and environmental exposure, making it suitable for both indoor and outdoor applications.
