This o-ring is supplied in black Viton® (FKM) 75 Shore A measuring an inside diameter of 74.2 mm (2.921 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 85.6 mm (3.37 in), catalogued under part number V5.7X74.2. It delivers dependable bidirectional sealing in a compact groove envelope.
The compound resists petroleum oils and fuels, aromatic hydrocarbons, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) offers very low compression set at elevated temperature and 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 is not the right choice where amines or hot water and steam are present.
It sees regular use in semiconductor equipment, oil and gas, and aerospace.
This item is sold individually under part number V5.7X74.2. Unit weight is approximately 11.742 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.
