-137 BLACK FKM 90D O-RING

Ordered as V90137, this is an AS568-137 black Viton® (FKM) 90 Shore A O-Ring measuring an inside diameter of 2.05 in (52.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.256 in (57.3 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to aggressive chemicals, chlorinated solvents, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is specified for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Exposure to low-molecular-weight organic acids or ketones and esters will shorten service life.

Common environments for this compound include high-temperature process equipment, semiconductor equipment, and chemical processing.

Order part number V90137, sold individually. Unit weight is approximately 1.7231 g and nominal inside diameter is listed as 2 1/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
