-259 BLUE FKM 75D O-RING

V75MD259 is an AS568-259 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 6.234 in (158.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.512 in (165.4 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against engine and transmission fluids, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It is not the right choice where amines or low-molecular-weight organic acids are present.

This o-ring meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Typical settings include high-temperature process equipment, chemical processing, and automotive fuel systems.

V75MD259 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
