FEPM (tetrafluoroethylene-propylene elastomer) is a specialist fluoroelastomer family offering resistance to amines, steam and caustic/alkaline media that attack standard FKM. FITCO markets FEPM generically and uses the AFLAS™ trademark only where the genuine branded polymer and supporting documentation confirm the claim.
Consult FITCO for FEPM sealing when standard FKM fails in steam, amine or caustic service — common in chemical processing, fertiliser production, refineries and selected oilfield applications.
| Hardness | 70–90 Shore A |
| Temperature Range | -10°C to 230°C continuous |
| Relevant Standards / Certifications | AS568, ISO 3601-1; AFLAS™ branding used only where genuine and documented |
FEPM fills a specific gap between standard FKM and FFKM — it handles amine and steam service that defeats FKM, without the cost premium of FFKM. Where chemical exposure is broader than amines/steam/caustics, FFKM should be evaluated instead.
Precision-molded circular seals available across FITCO's full specialty material range.
View O-Rings →FITCO uses the AFLAS™ name only when the actual supplied polymer is the genuine branded product and documentation supports that claim. Otherwise the material is described generically as FEPM.
No — FEPM is a specialist choice for specific steam, amine and caustic service. General hydrocarbon and fuel service typically remains better served by standard FKM.
