568-361 FKM 75 SQUARE CUT RINGS

APG stocks the SV70361, an AS568-361 black Viton® (FKM) 70 Shore A square profile Quad-Ring built to an inside diameter of 5.975 in (151.77 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 6.395 in (162.43 mm). A quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

Viton® (FKM) is specified here for outstanding high-temperature capability and very low compression set at elevated temperature. The compound resists aggressive chemicals, chlorinated solvents, and many acids. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

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

SV70361 ships individually. Nominal inside diameter is listed as 6 inch. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
