-474 BLACK FKM 75D O-RING

Part number V75474 is an AS568-474 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 24.94 in (633.48 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 25.49 in (647.45 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against many acids, aggressive chemicals, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with amines or low-molecular-weight organic acids.

Typical settings include oil and gas, high-temperature process equipment, and semiconductor equipment.

V75474 ships individually. Nominal inside diameter is listed as 25 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
