-315 BROWN FKM 75D O-RING

The VB75315 is an AS568-315 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 0.787 in (19.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.207 in (30.66 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It is not the right choice where hot water and steam or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across aerospace, high-temperature process equipment, and automotive fuel systems.

VB75315 ships individually. Unit weight is approximately 3.5887 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
