568-119 FKM 75 SQUARE CUT RINGS

APG stocks the SV70119, an AS568-119 black Viton® (FKM) 70 Shore A square profile Quad-Ring built to an inside diameter of 0.924 in (23.47 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.13 in (28.7 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

It resists petroleum oils and fuels, chlorinated solvents, and aggressive chemicals. Viton® (FKM) is widely chosen 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). Applications involving ketones and esters or hot water and steam call for a different compound.

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

SV70119 ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
