-231 BLACK FKM 75D O-RING

Part number V75231 is an AS568-231 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 2.609 in (66.27 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.887 in (73.33 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to many acids, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

Typical settings include chemical processing, aerospace, and oil and gas.

V75231 ships individually. Unit weight is approximately 4.023 g and nominal inside diameter is listed as 2 5/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
