-050 BROWN FKM 90D O-RING

APG stocks the VB90050, an AS568-050 brown Viton® (FKM) 90 Shore A O-Ring built to an inside diameter of 5.239 in (133.07 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.379 in (136.63 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Viton® (FKM) delivers very low compression set at elevated temperature, excellent resistance to compression set and permeation. The compound resists aromatic hydrocarbons, engine and transmission fluids, and chlorinated solvents. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or amines will shorten service life.

Maintenance and OEM teams specify it across chemical processing, semiconductor equipment, and automotive fuel systems.
