-430 BLACK CHEMOURS VITON 75D O-RING

APG stocks the VITON75430, an AS568-430 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 5.1 in (129.54 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 5.65 in (143.51 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with hot water and steam or amines.

Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and automotive fuel systems.
