-351 BLUE FKM 75D O-RING

Part number V75MD351 is an AS568-351 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 4.725 in (120.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.145 in (130.68 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against many acids, aggressive chemicals, and petroleum oils and fuels. Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or amines.

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 automotive fuel systems, chemical processing, and aerospace.
