FKM Rubber Products
Custom processed FKM rubber products, made in an in-house mould workshop where the tooling is designed and manufactured alongside the part.
Product Overview
Custom processed FKM rubber products, made in an in-house mould workshop where the tooling is designed and manufactured alongside the part. FKM resists a wide range of chemicals, oils and fuels, from aggressive acids through to industrial lubricants, and retains its structural integrity at elevated temperatures where other elastomers degrade. It is used in automotive and other high-performance applications.
Key benefits
Why Buyers Choose This Specification
Chemistry and Temperature Together
Most elastomers handle one or the other. FKM resists aggressive acids and industrial lubricants while also holding together at elevated temperature, which is what high-performance sealing actually requires.
Custom Processing With Own Tooling
The mould workshop is in-house, so a custom FKM part is designed, tooled and moulded by one party rather than three.
Resists Wear and Environmental Degradation
FKM's durability is inherent rather than applied, so parts keep performing through a long service life rather than degrading progressively.
Any FKM Part Not Just O-Rings
Custom processing means gaskets, diaphragms, bellows and moulded shapes, not only standard sealing rings.
Application scenarios
Where It Is Used
- Automotive high-temperature sealing components
- Chemical processing gaskets and diaphragms
- Fuel system components
- Industrial lubricant exposure applications
- Custom moulded FKM shapes to drawing
- Replacing parts that fail on chemistry or temperature
Who it is for
The Buyers This Product Suits
Automotive Engineers
Automotive is a named application, where under-bonnet temperature and fuel exposure both rule out cheaper elastomers.
Chemical Plant Operators
Resistance to aggressive acids and industrial lubricants is what keeps FKM parts in service where others are consumed.
Buyers Needing Custom FKM Shapes
With an in-house mould workshop, a part can be designed and tooled rather than substituted with a standard shape.
Problems it solves
What It Fixes
Parts Degrading at Elevated Temperature
FKM retains its structural integrity where temperatures soar, which is its primary selling point.
Chemical Attack on Moulded Components
Exceptional resistance to a wide range of chemicals, oils and fuels is inherent to the polymer.
No Tooling Route for a Custom Shape
The in-house mould workshop designs and manufactures the tool for the part.

Sourcing And Inspection
This product is supplied through TrueGlow Imaging, working with manufacturing partners whose facilities are visited and verified rather than taken on trust. In-process quality control and delivery supervision are available so goods are inspected before the container is sealed. Certifications quoted on this page are those stated on the product specification and belong to that product range rather than to our trading entity, so ask for the certificate covering your specific item.
Handling guide
Getting It Right First Time
Step 1
List the fluids and the maximum temperature before confirming FKM is the right grade.
Step 2
Send the part drawing or a sample so the mould can be designed to it.
Step 3
Confirm the hardness required in Shore A for the application.
Step 4
Discuss tooling cost against volume, since FKM parts are usually low volume and high value.
Step 5
Approve a first article before the production run.
Comparison
How It Compares In Our Range
FKM against the materials above and below it.
| FKM Rubber | Exceptional resistance to chemicals, oils and fuels with high-temperature stability. The standard high-performance elastomer. |
|---|---|
| NBR Rubber | Good oil resistance at much lower cost, but a narrower temperature and chemical range. |
| FFKM | Almost universal chemical resistance where FKM is still attacked, at a considerably higher price. |
FAQ
FKM Rubber Products Questions
Can you make custom FKM parts?
Yes. FKM rubber products are processed to custom requirements, and the mould is designed and manufactured in our own workshop.
What chemicals does FKM resist?
A wide range including aggressive acids, industrial lubricants, oils and fuels.
How does it perform at high temperature?
It retains its structural integrity and continues to perform where temperatures are elevated.
Which industries use FKM rubber?
Automotive among others, in high-performance applications.
Do we pay for the mould?
Tooling is quoted separately from the piece price. Confirm your volume so it can be amortised.
What quantities do you handle?
From sample quantities through to production runs.

Selecting an O-Ring Material NBR EPDM FKM or FFKM
Almost every seal failure is a material selection error rather than a dimensional one. The fluid and the temperature decide the elastomer, and the size is the easy part.
