568-229 FKM 75 SQUARE CUT RINGS

SV70229 is an AS568-229 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 2.359 in (59.92 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.637 in (66.98 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

This material stands up to chlorinated solvents, many acids, and aggressive chemicals. Viton® (FKM) is known for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where ketones and esters or hot water and steam are present.

It sees regular use in aerospace, semiconductor equipment, and chemical processing.

SV70229 ships individually. Nominal inside diameter is listed as 2 3/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
