568-260 FKM 75 SQUARE CUT RINGS

The SV70260 is an AS568-260 black Viton® (FKM) 70 Shore A square profile Quad-Ring measuring an inside diameter of 6.484 in (164.69 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 6.762 in (171.75 mm). This quad-ring resists spiral failure in reciprocating service thanks to its multi-lobe geometry.

As a material, Viton® (FKM) delivers excellent resistance to compression set and permeation, very low compression set at elevated temperature. This material stands up to petroleum oils and fuels, engine and transmission fluids, and aggressive chemicals. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or hot water and steam call for a different compound.

Typical settings include oil and gas, aerospace, and chemical processing.

This item is sold individually under part number SV70260. Nominal inside diameter is listed as 6 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
