FFKM o-rings and Perfluoroelastomer materials provide the highest temperature (up to 330 oC) and most universal chemical resistance of any rubber o-ring and gasket material. FFKM o-rings are utilized in the most demanding applications with dozens of compounds engineered for targeted application performance like low or high temperature, chemical compatibility and industry compliance. Our high performance High Temperature Resistant FFKM Rubber O-ring can satisfy your need in high temperature application and save your cost much
A series of Kalflon® FFKM O-Rings is developed by us Kaxite in order to help our customer can easily transfer from previous suppliers. Customers who used Kalrez® products before can also find their counterparts in our product list. We have chemical resistance compound FFKM O-rings series and temperature resistance compound FFKM O-rings series, and high purity FFKM series. Customized compound design is welcome by request. All data sheet can be found from our list below. We offer standard O-ring in AS-568, JIS B2401, JIS P, JIS V, JIS G, JIS S and international metric.
