568-393 FKM 75 SQUARE CUT RINGS

The SV70393 is an AS568-393 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 24.36 in (618.74 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) is widely chosen for very low compression set at elevated temperature, excellent resistance to compression set and permeation. The material holds up against engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Verify compatibility before use with low-molecular-weight organic acids or amines.

Typical settings include semiconductor equipment, automotive fuel systems, and high-temperature process equipment.

Reference part number SV70393 when ordering; the item is sold individually. 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.
