-376 BROWN FKM 90D O-RING

The VB90376 is an AS568-376 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 9.725 in (247.02 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 10.145 in (257.68 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against petroleum oils and fuels, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for outstanding high-temperature capability and long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. It should not be specified for service in low-molecular-weight organic acids or hot water and steam.

It sees regular use in chemical processing, semiconductor equipment, and automotive fuel systems.

This item is sold individually under part number VB90376. Unit weight is approximately 39.582 g and nominal inside diameter is listed as 9 3/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
