-377 BLACK AFLAS 80D O-RING

The A80377 is an AS568-377 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 9.975 in (253.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.395 in (264.03 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Aflas (TFE/P) is specified for exceptional resistance to amine-based additives and high-temperature steam capability that most fluoroelastomers cannot match. Expect good resistance to high-temperature steam, amines and corrosion inhibitors, and hot water. Service temperature is rated from -25°F (-31.7°C) through 450°F (232.2°C). Exposure to some chlorinated solvents or aromatic hydrocarbons will shorten service life.

Typical settings include geothermal equipment, downhole tooling, and power generation.

A80377 ships individually. Unit weight is approximately 29.2701 g and nominal inside diameter is listed as 10 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
