-431 BLACK FKM 75D O-RING

Part number V70431 is an AS568-431 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 5.225 in (132.72 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.775 in (146.69 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is valued for very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. It resists chlorinated solvents, aromatic hydrocarbons, and many acids. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.

Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and automotive fuel systems.

V70431 ships individually. Unit weight is approximately 31.222 g. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
