The V70388 is an AS568-388 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 18.953 in (481.41 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 19.373 in (492.07 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to aggressive chemicals, petroleum oils and fuels, and chlorinated solvents. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

You will find this material specified across high-temperature process equipment, chemical processing, and aerospace.
