Interplast 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 are chemically inert to attack by most
chemicals and acids except alkali metals and certain
fluorinated materials at elevated temperatures.

PTFE rings can be supplied in Virgin material or with a filler
to enhance certain properties.

In mechanical applications PTFE with a filler often improves the wear resistance, initial deformation and reduces creep and often increases stiffness and thermal conductivity.

Interplast provides standard and custom fabricated sizes to our customer's exact specifications. These sealing components are produced to the highest industry standards.
