Product Description

Oill-free Air compressor ptfe piston cup seals

PTFE Ring - We don't offer standard size or stocks, we do custom make only.

Dechengwang produces a complete and full line of PTFE rings for multiple sealing applications in corrosive and high temperature environments(-400°F to +500°F).

These include piston rings, compressor rings, hydraulic seal rings, o-rings, v-rings, ring bearings, back up rings, lantern rings and seals.
PTFE rings can be supplied in Virgin material or with a filler to enhance certain properties.
Regular Filler including: - Glass fiber - Carbon - graphite.
In mechanical applications PTFE with a filler often improves the wear resistance, initial deformation and reduces creep and often increases stiffness and thermal conductivity.
