-401 BROWN FKM 75D O-RING

VB75401 is an AS568-401 brown Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.025 in (51.44 mm). In service, this o-ring remains the most cost-effective sealing element available for pressurized assemblies.

This material stands up to engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. Viton® (FKM) offers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or amines.

You will find this material specified across high-temperature process equipment, semiconductor equipment, and chemical processing.

Stocked as VB75401 and sold individually. Nominal inside diameter is listed as 1 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
