568-334 FKM 75 SQUARE CUT RINGS

This square-cut ring is supplied in AS568-334 black Viton® (FKM) 70 Shore A measuring an inside diameter of 2.6 in (66.04 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 3.02 in (76.71 mm), catalogued under part number SV70334. It presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

Viton® (FKM) is specified here for outstanding high-temperature capability and very low compression set at elevated temperature. It resists engine and transmission fluids, aggressive chemicals, and aromatic hydrocarbons. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Applications involving low-molecular-weight organic acids or hot water and steam call for a different compound. The profile itself contributes simple lathe-cut manufacture at low tooling cost and a rectangular section that will not roll in the groove. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

It sees regular use in automotive fuel systems, aerospace, and high-temperature process equipment.
