Perfluoroelastomer (FFKM/FFPM) parts resist over 1,800 different chemicals, including concentrated nitric acid, sodium hydroxide, ethylene diamine and steam while offering the high temperature stability of PTFE (327°C).

Certain grades have a maximum continuous service temperature of 327 °C (621 °F). They are commonly used to make O-rings and gaskets that are used in applications that involve contact with hydrocarbons or highly corrosive fluids, or when a …

Feb 1, 2024 · Machine parts like seals and o-rings benefit from FFPM’s flexibility. This material adapts well to dynamic environments within machinery, maintaining a tight seal even during movement or temperature changes. Parts made from FFPM are often found in …

O-Rings from FTL Technology. The O-ring seal is widely used across virtually every industry, due to its incredibly versatility. From general engineering through to critical oil and gas applications, there is an O-ring to stand up to all kinds of pressures, temperatures and media exposure. FTL Technology can source O-rings in...

Mar 12, 2025 · Learn the differences between FFPM and FFKM O-rings: properties, applications, and benefits in this complete guide by Ultima.

The O-ring is commonly used in and has an operating temperature range from -20 ºC to 270 ºC. O-rings 474858 are indicated as 51142 and have a DIN 3771 Size of 85.09x5.33.

Global O-Ring and Seal provides high-performance FFKM o-rings for your demanding applications. Our FFKM sealing solutions include Kalrez®, Chemraz®, and PERFREZ®. Kalrez® perfluoroelastomer (FFKM) parts resist over 1,800 different chemicals, while offering the high temperature stability.

Perfluoroelastomer (FFKM) o-rings are a terpolymer of perfluoro(methyl vinyl) ether, tetrafluoroethylene, and perfluoroalkyl ether. They have the elasticity and thermal and chemical stability of PTFE. Their long-term efficacy can improve production efficiency and reduce maintenance costs.

Perfluororubber also has excellent air tightness (vacuum resistance up to 1.33X10-7-1.33X10-8pa), high cleanliness and ionomer resistance, which are widely used in semiconductor industry.

Sep 7, 2022 · Fluoroelastomers can be fabricated into O-rings, seals, hoses, and so much more for a variety of industries. These polymers enhance sealing reliability, safety, and prevent material leakages in a range of high-performance applications.
