Ordered as V75MD240, this is an AS568-240 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 3.734 in (94.84 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.012 in (101.9 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments and industry benchmark where nitrile reaches its thermal limit. This material stands up to engine and transmission fluids, aromatic hydrocarbons, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to low-molecular-weight organic acids or amines will shorten service life.
This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. It sees regular use in high-temperature process equipment, chemical processing, and semiconductor equipment.
Stocked as V75MD240 and sold individually. Review your operating media and conditions against this specification before installation.
