-240 BLACK AFLAS 80D O-RING

APG stocks the A80240, an AS568-240 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 3.734 in (94.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.012 in (101.9 mm). An 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 high-temperature steam capability that most fluoroelastomers cannot match. It resists brake fluids and phosphate esters, hot water, and high-temperature steam. Published continuous service range is -25°F (-31.7°C) to 450°F (232.2°C). It should not be specified for service in low-temperature dynamic service or aromatic hydrocarbons.

Common environments for this compound include chemical processing, geothermal equipment, and downhole tooling.

A80240 ships individually. Unit weight is approximately 0.0053 g and nominal inside diameter is listed as 3 3/4 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
