Product Specification

-
Ordered as A80311, this is an AS568-311 black Aflas (TFE/P) 80 Shore A O-Ring supplied with an inside diameter of 0.537 in (13.64 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 0.957 in (24.31 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Aflas (TFE/P) is specified here for excellent electrical insulating properties and proven performance in aggressive downhole environments. This material stands up to high-temperature steam, hot water, and sour gas and hydrogen sulfide. The material carries a published service range of -25°F (-31.7°C) to 450°F (232.2°C). Exposure to low-temperature dynamic service or some chlorinated solvents will shorten service life.

Typical settings include chemical processing, downhole tooling, and geothermal equipment.

This item is sold individually under part number A80311. As always, verify media compatibility and operating conditions against the requirements of your specific application.
