-372 BLACK FKM 75D O-RING

The V75372 is an AS568-372 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 8.725 in (221.62 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 9.145 in (232.28 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

It sees regular use in aerospace, automotive fuel systems, and chemical processing.

Stocked as V75372 and sold individually. Nominal inside diameter is listed as 8 3/4 inch. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
