-044 BROWN FKM 75D O-RING

Part number VB75044 is an AS568-044 brown Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 3.739 in (94.97 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 3.879 in (98.53 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for long service life in hot, chemically aggressive environments and outstanding high-temperature capability. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or hot water and steam are present.

Common environments for this compound include oil and gas, aerospace, and automotive fuel systems.
