568-024 FKM 75 SQUARE CUT RINGS

This square-cut ring is supplied in AS568-024 black Viton® (FKM) 70 Shore A with an inside diameter of 1.114 in (28.3 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.254 in (31.85 mm), catalogued under part number SV70024. It seals with a broad flat contact band instead of the line contact of a round-section ring.

Viton® (FKM) is specified here for long service life in hot, chemically aggressive environments, excellent resistance to compression set and permeation. Expect good resistance to petroleum oils and fuels, aromatic hydrocarbons, and engine and transmission fluids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with hot water and steam or amines. The profile itself contributes greater resistance to extrusion than a round section of the same size and a flat contact band that spreads sealing load across a wider area. Note that a square section is less suited to high-speed rotary service, where the larger contact area raises friction and heat.

You will find this material specified across chemical processing, automotive fuel systems, and high-temperature process equipment.

Reference part number SV70024 when ordering; the item is sold individually. Nominal inside diameter is listed as 1 1/8 inch. Review your operating media and conditions against this specification before installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
