PMETemp range-30°C
200°C
Hallite PME back-up rings are uncut back-up rings made from specific conditioned PTFE to be assembled into one-piece external grooves. PME back-up rings 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… |
