Frequently Asked Questions

1: What is FKM gasket?

A: FKM gasket, also known as Viton / FPM gasket, is a high-performance fluoroelastomer static sealing part, made by compression molding or cutting. It features excellent resistance to high temperature, oil, fuel, solvent, ozone and aging.

 Q2: What is the temperature range of standard FKM gasket?

A: Continuous working temperature: **-20°C ~ +200°C**. Intermittent peak temperature can reach 230°C. Special low-temperature FKM grade can work down to -40°C.

Q3: What hardness is available for FKM gasket?

A: Common hardness range: **55–90 Shore A**. 70 Shore A is the most popular grade for general static gaskets, like our custom green molded FKM gasket.

 Q4: What media does FKM /Viton gasket resist?

A: It works well with mineral oil, synthetic oil, gasoline, diesel, biodiesel, hydraulic fluid, aromatic solvents, dilute acid, hot air, ozone and UV.

Q5: What media is NOT suitable for FKM gasket?

A: Not recommended for hot concentrated alkali, ketones, esters, some amines and high-pressure saturated steam. Choose AFLAS, EPDM or FFKM for these conditions.

Q6: Can you make custom FKM gaskets?

A: Yes. We support custom molded FKM gaskets according to your drawings or samples, including custom shape, size, color and hardness. Green 70 Shore A is available as shown.

 Q7: What certifications can you provide?

A: RoHS, REACH, FDA, IATF16949 documents are available upon request.

Q8: What industries use FKM gaskets?

A: Widely used in automotive, oil & gas, petrochemical, chemical, hydraulic, pump & valve, food & pharmaceutical and compressor systems.

Q9: What is the difference between FKM and FFKM gasket?

A: FKM is cost-effective for most high-temp oil & chemical conditions. FFKM (perfluoroelastomer) offers superior chemical resistance and higher temperature resistance with higher cost.

 Q10: Is FKM gasket for static or dynamic sealing?

A: FKM gasket is mainly designed for **static sealing (flange, housing joint)**. For dynamic shaft sealing, FKM oil seals are recommended.
