The VB75920 is an AS568-920 brown Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 1.475 in (37.47 mm), a cross section of 0.118 in (3 mm), and an outside diameter of 1.711 in (43.46 mm). This o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
Expect good resistance to aggressive chemicals, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is specified for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).
Maintenance and OEM teams specify it across aerospace, oil and gas, and chemical processing.
Order part number VB75920, sold individually. Unit weight is approximately 1.8492 g and nominal inside diameter is listed as 1 1/4 inch. Check the compound against your process media, pressure and temperature before committing to a design.
