The V4X205 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 205 mm (8.071 in), a cross section of 4 mm (0.157 in), and an outside diameter of 213 mm (8.39 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
The compound resists petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, long service life in hot, chemically aggressive environments. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with low-molecular-weight organic acids or hot water and steam.
You will find this material specified across semiconductor equipment, high-temperature process equipment, and aerospace.
Reference part number V4X205 when ordering; the item is sold individually. Unit weight is approximately 14.837 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
