-259 BLACK CHEMOURS VITON 75D O-RING

The VITON75259 is an AS568-259 black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 6.234 in (158.34 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.512 in (165.4 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against engine and transmission fluids, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or amines.

Typical settings include automotive fuel systems, chemical processing, and semiconductor equipment.

Reference part number VITON75259 when ordering; the item is sold individually. Unit weight is approximately 9.176 g and nominal inside diameter is listed as 6 1/4 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
