FFKM O-Rings
Rocket Seals distributes perfluoroelastomer O-rings and seals made from various FFKM materials. Perfluoroelastomer (FFKM) O-rings and seals have the highest temperature tolerance and chemical resistance of any O-ring or seal.
At Rocket Seals, we are committed to offering superior customer service. We see ourselves as your partner, providing technical expertise in selecting FFKM O-rings and seals that meet your specifications and are appropriate for your applications. We stock a large inventory of perfluoroelastomer (FFKM) O-rings and perfluoroelastomer (FFKM) seals from leading manufacturers.
Benefits & Characteristics of FFKM O-rings and Seals
Perfluoroelastomer (FFKM) is a synthetic rubber with higher amounts of fluorine than the standard FKM. This higher fluorine concentration gives FFKM the greater high temperature and chemical resistance you need.
FFKM has a high-temperature rating of up to 620° F and nearly universal chemical compatibility including highly corrosive fluids and hydrocarbons. Additionally, FFKM withstands environments where oxygen is present for many hours and has a generally long service life. This combination of high-performance capabilities makes FFKM seals and O-rings the best choice for challenging applications.
We offer FFKM O-rings and seals in Simriz®, Kalrez® and Chemraz®.
Kalrez®
Kalrez® is a DuPont trademark. It is resistant to over 1,800 different harsh chemicals while offering the high-temperature stability of Teflon™. The temperature range for these compounds is usually -4°F to 615°F.
Chemraz®
Chemraz® is the Green Tweed version of Kalrez®. It is also a member of the perfluoroelastomer polymer family Simriz®. Chemraz® can handle high heat and is chemical and solvent-resistant. Its defining properties are exceptional resistance to steam and performance in low-temperature environments, as well as availability.
Simriz®
Simriz® is typically a lower-cost alternative to both Kalrez® and Chemraz®. This compound does well in aggressive environments like dry process chemistries and reactive plasmas. Simriz® has excellent heat resistance, great low-temperature performance, and amine resistance.
