Low Temperature

New FKM down to -60°

Very broad chemical resistance, low compression end set and suitable for extremely high thermal stresses. Temperature range of -60°C to +250°C!
Material with different hardness values and suitable for use in explosive decompression applications.


The new perfluoroelastomer (FFKM) with the chemical resistance of PTFE and the resilience and sealing characteristics of an elastomer. Benefits: Low temperature down to -40°C , explosive decompression resistant.

PEEK - Polyether ether ketone

An engineered thermoplastic material exhibiting excellent chemical resistance, low weight,low coefficient of thermal expansion, good wear and abrasion resistance, no water absorption and capable of performing in high pressure, high temperature applications as a seal or as an anti-extrusion device.
PEEK applications include: Anti-extrusion devices, Sealing components, Tribological components, Valve Seat Seals, Structural components, Electrical components and Insulators.
The material is well suited for applications with wide extremes of temperature, ranging from -100°C to +300°C.

Composite Materials

PEEK bonded to carbon fibre: Carbon fibre materials for the highest safety, reliability and cost effectiveness requirements. Increases the service life and reduces operating costs (life cycle cost).
PEEK or modified PEEK parts can replace metal parts.
This material combines a high strength similar to that of metal with an enormous weight advantage.

NEW: Chemflon® 1285

FDA compliant seals at an exceptionally affordable price: KED Seals presents CHEMFLON® 1285, a new FEPM grade which is FDA compliant. This material is significantly superior to other materials such as silicone, EPDM and FKM especially under aggressive conditions, and much more economical than FFKM materials.

The currently biocompatibility requirements according to the USP (United States Pharmacopeia) Class VI can be met as well. Using CHEMFLON® 1285 can increase the average service life, avoiding expensive and unplanned downtime, leaks and contamination of product.
