Interplast O-Rings are produced with 100% Virgin PTFE and fabricated to extremely close tolerances and to the highest industry and military specifications.

PTFE O-Rings are impervious to harsh chemicals, acids and gases.

PTFE O-Rings are an ideal solution for sealing applications where there are high temperatures and corrosive liquids or gases involved.

Interplast offers a wide range of standard, custom and metric sizes produced in Virgin grade and reinforced fillers such as glass, carbon, graphite and bronze. PTFE rings are available up to 48" OD.

Here is a listing of some standard O-Ring sizes:
