-401 BLACK CHEMOURS VITON 75D O-RING

VITON75401 is an AS568-401 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 1.475 in (37.47 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 2.025 in (51.44 mm). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists petroleum oils and fuels, many acids, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. 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.

Maintenance and OEM teams specify it across aerospace, semiconductor equipment, and automotive fuel systems.
