VB75031 is an AS568-031 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 1.739 in (44.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.879 in (47.73 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to many acids, petroleum oils and fuels, and aggressive chemicals. Viton® (FKM) offers excellent resistance to compression set and permeation, outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

You will find this material specified across chemical processing, semiconductor equipment, and oil and gas.

VB75031 ships individually. Unit weight is approximately 0.765 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
