The o-ring delivers dependable bidirectional sealing in a compact groove envelope.
PTFE-Encapsulated Viton® is known for chemical inertness of PTFE with the memory of a rubber o-ring, excellent resistance to permeation and contamination. The material holds up against steam, nearly all process chemicals, and strong acids and solvents. The material carries a published service range of -75°F (-59.4°C) to 400°F (204.4°C). Applications involving installation over sharp edges without care or service requiring tight-radius dynamic flexing call for a different compound.
Typical settings include semiconductor equipment, chemical processing, and pharmaceutical manufacturing.
Order part number TEV80250, sold individually. Nominal inside diameter is listed as 5 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
