-312 BLUE FKM 75D O-RING

Part number V75MD312 is an AS568-312 blue Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.6 in (15.24 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.02 in (25.91 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Viton® (FKM) is valued for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. The material holds up against aromatic hydrocarbons, aggressive chemicals, and chlorinated solvents. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to amines or low-molecular-weight organic acids will shorten service life.

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. You will find this material specified across oil and gas, aerospace, and chemical processing.
