568-281 FEP ENCAPSULATED VITON ORING

APG stocks the TEV80281, an AS568-281 black PTFE-Encapsulated Viton® 90 Shore A O-Ring measuring an inside diameter of 14.984 in (380.59 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 15.262 in (387.65 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

It resists aggressive oxidizers, nearly all process chemicals, and strong acids and solvents. That behavior comes from the compound itself: PTFE-Encapsulated Viton® offers excellent resistance to permeation and contamination, a non-stick sealing surface that resists fouling. Rated temperature range runs from -75°F (-59.4°C) to 400°F (204.4°C) in continuous service. Applications involving installation over sharp edges without care or service requiring tight-radius dynamic flexing call for a different compound.

Typical settings include aggressive-media valves and pumps, chemical processing, and semiconductor equipment.

Stocked as TEV80281 and sold individually. Nominal inside diameter is listed as 15 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
