Fkm O Ring

Viton dai el and technoflon are brands for fpm polymers.

Fkm o ring.

Fkm o rings aka viton o rings offer an impressive range of chemical compatibility and high temperature resistance up to 400f with hundreds of specialty compounds available for specific application performance making fkm an ideal o ring material choice in a number of applications. Parker s fluorocarbon fkm fpm o rings are compatible with oils and gases hydraulic oil and fuels. Fkm o rings 60 shore a these fkm o rings can handle temperatures from 15 c to 200 c and are good resistance to oils and fats. This rubber is used in applications that need o rings that are resistant to high temperatures and chemical attacks.

Fkm o rings 70 shore a black. Fkm fluorocarbon is a family of fluoroelastomer materials defined by the astm international standard d1418. Ffkm o rings perfluoroelastomer ffkm o rings are the highest high performance family of o rings with the highest temperature up to 620f and ultimate chemical resistance. Viton o ring and seal performance cost benefit makes it the second most popular sealing material.

It is equivalent to fpm by iso din 1629 standard. Low temp f high temp f highlight features. The characteristics of fkm o rings and seals made them highly desirable in many applications. Fkm o rings and sealing gaskets are made of fluorocarbon elastomers and are extensive used over a wide span of industries.

All of the designations stand for one single base material which is fluoro rubber. The hardness of this o ring is 60 shore. Fluoroelastomer viton fkm offers a wide range of resistance to chemicals oil and heat with situational service life above 200 c. Originally developed by dupont viton fkms are today also produced by daikin chemical 3m s dyneon dyneon fluoroelastomers solvay specialty polymers halopolymer elaftor.

Fkm applications fluorocarbon o rings should be considered for use in aircraft automobile and other mechanical devices requiring maximum resistance to elevated temperatures and to many fluids. All fkms contain vinylidene fluoride as a monomer.
