-379 BROWN FKM 75D O-RING

VB75379 is an AS568-379 brown Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 10.975 in (278.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 11.395 in (289.43 mm). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Viton® (FKM) is specified here for very low compression set at elevated temperature and industry benchmark where nitrile reaches its thermal limit. The material holds up against chlorinated solvents, petroleum oils and fuels, and aromatic hydrocarbons. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and semiconductor equipment.

VB75379 ships individually. Unit weight is approximately 40.308 g and nominal inside diameter is listed as 11 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
