4MM CS X 37MM ID BLACK FKM 75D

V4X37 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 37 mm (1.457 in), a cross section of 4 mm (0.157 in), and an outside diameter of 45 mm (1.77 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

As a material, Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The compound resists chlorinated solvents, aromatic hydrocarbons, and aggressive chemicals. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving low-molecular-weight organic acids or ketones and esters call for a different compound.

You will find this material specified across oil and gas, semiconductor equipment, and chemical processing.

V4X37 ships individually. Unit weight is approximately 2.9616 g. Review your operating media and conditions against this specification before installation. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
