Product Specification

-
Part number VITON75373 is an AS568-373 black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 8.975 in (227.97 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.395 in (238.63 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Viton® (FKM) is valued for the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. This material stands up to engine and transmission fluids, many acids, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.

It sees regular use in aerospace, chemical processing, and semiconductor equipment.

Order part number VITON75373, sold individually. Unit weight is approximately 29.996 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need?
