-041 BROWN FKM 90D O-RING

The VB90041 is an AS568-041 brown Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 2.989 in (75.92 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.129 in (79.48 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The material holds up against many acids, aggressive chemicals, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is known for long service life in hot, chemically aggressive environments 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. It is not the right choice where ketones and esters or hot water and steam are present.

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and chemical processing.
