Ordered as V75233, this is an AS568-233 black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 2.859 in (72.62 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 3.137 in (79.68 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.
The material holds up against chlorinated solvents, many acids, and engine and transmission fluids. Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in amines or low-molecular-weight organic acids.
Typical settings include semiconductor equipment, aerospace, and chemical processing.
V75233 ships individually. Unit weight is approximately 4.3 g and nominal inside diameter is listed as 2 7/8 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.
