-124 BLUE FKM 75D O-RING

Ordered as V75MD124, this is an AS568-124 blue Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 1.237 in (31.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.443 in (36.65 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. It resists aggressive chemicals, chlorinated solvents, and many acids. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C).

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across semiconductor equipment, high-temperature process equipment, and aerospace.

V75MD124 ships individually. Nominal inside diameter is listed as 1 1/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
