-118 BROWN FKM 90D O-RING

This o-ring is supplied in AS568-118 brown Viton® (FKM) 90 Shore A built to an inside diameter of 0.862 in (21.89 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.068 in (27.13 mm), catalogued under part number VB90118. It creates a positive seal at flange, piston and rod interfaces without added hardware.

The compound resists many acids, aromatic hydrocarbons, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers 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). Verify compatibility before use with low-molecular-weight organic acids or ketones and esters.

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and automotive fuel systems.

Order part number VB90118, sold individually. Unit weight is approximately 0.976 g and nominal inside diameter is listed as 7/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
