568-437 FKM 75 SQUARE CUT RINGS

APG stocks the SV70437, an AS568-437 black Viton® (FKM) 70 Shore A square profile Quad-Ring with an inside diameter of 5.975 in (151.77 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 6.525 in (165.74 mm). A quad-ring uses a four-lobed profile to create two sealing surfaces per side, reducing the squeeze needed to seal.

As a material, Viton® (FKM) is known for outstanding high-temperature capability and very low compression set at elevated temperature. Expect good resistance to chlorinated solvents, many acids, and aromatic hydrocarbons. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service.

Common environments for this compound include high-temperature process equipment, chemical processing, and semiconductor equipment.

SV70437 ships individually. Nominal inside diameter is listed as 6 inch. Review your operating media and conditions against this specification before installation.
