Ordered as TEV80354, this is an AS568-354 black PTFE-Encapsulated Viton® 90 Shore A O-Ring measuring an inside diameter of 5.1 in (129.54 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.52 in (140.21 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists steam, strong acids and solvents, and nearly all process chemicals. PTFE-Encapsulated Viton® is valued for a non-stick sealing surface that resists fouling and long service life in aggressive chemical duty. Service temperature is rated from -75°F (-59.4°C) through 400°F (204.4°C). It is not the right choice where service requiring tight-radius dynamic flexing or installation over sharp edges without care are present.
You will find this material specified across chemical processing, semiconductor equipment, and pharmaceutical manufacturing.
This item is sold individually under part number TEV80354. Nominal inside diameter is listed as 5 1/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
