Characteristics and performance

Hallite PME back-up rings are uncut back-up rings made from specific conditioned PTFE to be assembled into one-piece external grooves. They are designed to support o-rings mainly in static applications.

The cold flow feature of the specially conditioned virgin PTFE grade reliably closes the extrusion gap and protects the o-ring from extruding into the gap and helps to reasonably increase the acceptable system pressure.
