Product Specification

-
APG stocks the VITON75353, an AS568-353 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 4.975 in (126.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.395 in (137.03 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against chlorinated solvents, aggressive chemicals, and many acids. 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. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

Common environments for this compound include automotive fuel systems, high-temperature process equipment, and oil and gas.

Reference part number VITON75353 when ordering; the item is sold individually. Unit weight is approximately 16.913 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
