568-163 FKM 75 SQUARE CUT RINGS

APG stocks the SV70163, an AS568-163 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 5.987 in (152.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 6.193 in (157.3 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

The compound resists aggressive chemicals, chlorinated solvents, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is valued for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with hot water and steam or low-molecular-weight organic acids.

It sees regular use in semiconductor equipment, high-temperature process equipment, and aerospace.
