APG stocks the V4X23, a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 23 mm (0.906 in), a cross section of 4 mm (0.157 in), and an outside diameter of 31 mm (1.22 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
It resists engine and transmission fluids, aromatic hydrocarbons, and many acids. Viton® (FKM) is known for long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Applications involving hot water and steam or ketones and esters call for a different compound.
Typical settings include semiconductor equipment, aerospace, and oil and gas.
Stocked as V4X23 and sold individually. Unit weight is approximately 1.953 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
