FKM Rubber Products

FKM rubber products processed to custom requirements, backed by an in-house mold workshop where the tooling for your own part can be designed and manufactured. FKM is selected for its resistance to a wide range of chemicals, oils and fuels, from aggressive acids through to industrial lubricants, so components keep performing rather than degrading in contact with the process. It also retains its structural integrity at elevated temperatures, which is what qualifies it for hot service positions, and it resists wear and environmental degradation so the part lasts in continuous duty. Automotive work is a typical application area.

Specifications are configured per project. Send your drawing, capacity or duty requirement and the build will be confirmed in writing with the quotation.
Why It Works

Key Benefits

Custom processing means the part is made to your geometry instead of being selected from a standard shape

An in-house mold workshop lets the tooling for your part be designed and made in the same place it will be moulded

Chemical resistance across acids oils and fuels lets one material cover mixed media in the same machine

Temperature stability keeps the part serviceable where heat would degrade a general purpose compound

Wear and environmental resistance extends the interval between part replacements in continuous duty

Problems

Problems It Solves

General purpose compounds are attacked by acids or lubricants and the part fails early

Standard shapes do not match the geometry the application actually needs

Sourcing tooling and moulding separately slows every change to the part

Parts that soften at elevated temperature lose their function in hot positions

Short part life in continuous duty forces frequent stoppages for replacement

Comparison

How It Compares

NBR rubber part

FKM is specified where acids or elevated temperature would put nitrile beyond its service range

FFKM part

FFKM is reserved for the most aggressive chemistry while FKM covers oils fuels and acids at lower cost

Standard catalogue part

Custom processing produces the geometry the application needs instead of the nearest available shape

FAQ

FKM Rubber Products FAQ

Can you process FKM parts to our own design

Yes. FKM rubber products are processed to custom requirements, and the mould for your part can be designed and manufactured in the in-house mold workshop.

What chemicals does FKM resist

A wide range of chemicals, oils and fuels, from aggressive acids through to industrial lubricants.

How does FKM behave at high temperature

It retains its structural integrity and continues to function at elevated temperatures, which is why it is chosen for hot service positions.

Do you make the mould as well as the part

Yes. The mold workshop is in house, so the mould for your part is designed and manufactured alongside the production work.

How long will an FKM part last in service

FKM resists wear and environmental degradation, so service life is longer than a general purpose compound in the same duty. Actual life depends on your conditions.

What tolerance and lead time can we expect

Both depend on the part geometry and tooling status, and both are confirmed in writing with the quotation.
