568-250 FEP ENCAPSULATED VITON ORING

Ordered as TEV80250, this is an AS568-250 black PTFE-Encapsulated Viton® 90 Shore A O-Ring supplied with an inside diameter of 4.984 in (126.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.262 in (133.65 mm). 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.
