-171 BLUE FKM 75D O-RING

Part number V75MD171 is an AS568-171 blue Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 7.987 in (202.87 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 8.193 in (208.1 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against aggressive chemicals, petroleum oils and fuels, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability, excellent resistance to compression set and permeation. 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 amines or low-molecular-weight organic acids.

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.
