Upgrade Your Seals: A Guide to FEP Encapsulated O-Rings and Their Applications In harsh environments where reliable sealing is needed, FEP encapsulated O rings are found to be widely used by engineers and designers for their excellent performances. These innovative rings have combined the strengths of FEP (fluorinated ethylene propylene) like chemical resistance with those of an elastomeric core such as its ability to create a sealable bond at the interface between two surfaces which are inherently not compatible in nature. #FEPencapsulatedorings 🌐https://www.tumblr.com/sealmax/745649111395713024/upgrade-your-seals-a-guide-to-fep-encapsulated?source=share
