-343 BLACK AFLAS 80D O-RING

A80343 is an AS568-343 black Aflas (TFE/P) 80 Shore A O-Ring with an inside diameter of 3.725 in (94.62 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 4.145 in (105.28 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to strong bases, amines and corrosion inhibitors, and hot water. That behavior comes from the compound itself: Aflas (TFE/P) delivers strong resistance to rapid gas decompression and high-temperature steam capability that most fluoroelastomers cannot match. Continuous operating temperature is published at -25°F (-31.7°C) to 450°F (232.2°C).

Typical settings include geothermal equipment, chemical processing, and power generation.

A80343 ships individually. Unit weight is approximately 11.3086 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
