-920 BROWN FKM 90D O-RING

This o-ring is supplied in AS568-920 brown Viton® (FKM) 90 Shore A supplied with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.711 in (43.46 mm), catalogued under part number VB90920. It compresses into its gland to block fluid or gas migration across a joint.

The compound resists engine and transmission fluids, many acids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and high-temperature process equipment.

Stocked as VB90920 and sold individually. Unit weight is approximately 1.9509 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
