What is a PTFE backup ring?
PTFE Back-Up Rings are used to prevent the extrusion of elastomeric o-rings in a dynamic or static sealing application. Most o-rings will begin to wear when subjected to increasing temperatures and pressures and will begin to extrude into any gaps next to the o-ring groove.
