FKM Seals & O-Rings: How to Select the Right Seal for Heat and Chemicals?

Need sealing solutions for extreme heat or aggressive chemicals? FKM-fokoj kaj O-ringoj might be exactly what your application demands.
FKM O-rings resist heat up to 250°C and offer unmatched chemical durability—ideal for fuel systems, hydraulics, and industrial equipment.

Let’s explore how FKM seals work, what makes them different, and how to choose the best one for your system.

What makes FKM O-rings better than standard rubber seals?

Not all seals can handle extreme environments—FKM seals are engineered for them.
They outperform standard rubber in heat, pressure, and chemical exposure.

Here’s how FKM compares to typical elastomers like NBR or EPDM:

What industries rely on FKM seals?

FKM seals are essential for industries where failure is not an option.
They’re especially valuable where sealing must remain stable under extreme heat or corrosive chemicals.

FKM O-Ring Applications in Automotive, Aerospace & Industrial Systems

• Aŭtomobilo: Engines, transmission, fuel injection
• Aerospaco: Jet engines, hydraulic circuits
• Industriaj pumpiloj: Oil seals, rotating equipment
• Petrolo & Gaso: Chemical plants, drilling systems

Can FKM seals handle high temperatures?

Absolutely—FKM is designed for it.
Its resistance up to 250°C makes it ideal for heat-critical systems.

Unlike NBR or silicone that degrade under heat, FKM:

• Retains flexibility in hot zones
• Doesn’t crack under thermal cycling
• Handles hot oils, fuels, and vapors without swelling

That’s why it’s trusted in turbochargers, jet engines, and refinery valves.

How do I select the right FKM seal?

Picking the best FKM seal depends on matching it to your working conditions.
