-166 BLUE FKM 75D O-RING

V75MD166 is an AS568-166 blue Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 6.737 in (171.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.943 in (176.35 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The compound resists petroleum oils and fuels, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is known for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where amines or low-molecular-weight organic acids are present.

This item 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 automotive fuel systems, chemical processing, and aerospace.

V75MD166 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
