DLSEALS piston ring for oil-free air compressor
DLSEALS 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.
Properties
