-328 BLACK FKM 75D O-RING

The V75328 is an AS568-328 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 1.85 in (46.99 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 2.27 in (57.66 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists aromatic hydrocarbons, many acids, and aggressive chemicals. Viton® (FKM) is valued for excellent resistance to compression set and permeation, 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 low-molecular-weight organic acids or amines.

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