What is PTFE encapsulated O-ring?

Update:2019-01-03

DSH Seals share with you that it is the second advantage of encapsulated O-ring with Teflon. The O-ring has the chemical resistance of PTFE and maintains the original flexibility and elasticity of the rubber seal. If the ratio of rubber to PTFE is high, it will work easily on both static and dynamic seals, and the contact area will increase, reducing the possibility of failure due to compression set. . When used as a dynamic seal, Teflon also reduces friction due to the relationship of the sealing material, especially friction.

The coating of the polytetrafluoroethylene can be carried out by various methods such as bonding into an open sleeve, a seaming sleeve or casting into a cover layer. For larger seals, the cladding can be in the form of a welded seamless Teflon tube (Figure 1 shows a typical Teflon-coated O-ring configuration)
