-126 BROWN FKM 75D O-RING

Part number VB75126 is an AS568-126 brown Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to engine and transmission fluids, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is valued for outstanding high-temperature capability and the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

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

Order part number VB75126, sold individually. Unit weight is approximately 1.3099 g and nominal inside diameter is listed as 1 3/8 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
