-371 BROWN FKM 90D O-RING

The VB90371 is an AS568-371 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 8.475 in (215.27 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 8.895 in (225.93 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to engine and transmission fluids, many acids, and aggressive chemicals. Viton® (FKM) delivers very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Exposure to low-molecular-weight organic acids or amines will shorten service life.

Typical settings include high-temperature process equipment, semiconductor equipment, and chemical processing.
