-352 BLUE FKM 75D O-RING

This o-ring is supplied in AS568-352 blue Viton® (FKM) 75 Shore A with an inside diameter of 4.85 in (123.19 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.27 in (133.86 mm), catalogued under part number V75MD352. It seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The compound resists aromatic hydrocarbons, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in ketones and esters or amines.

The compound 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 chemical processing, aerospace, and high-temperature process equipment.

Reference part number V75MD352 when ordering; the item is sold individually. Nominal inside diameter is listed as 4 7/8 inch. Review your operating media and conditions against this specification before installation.
