568-473 FKM 75 SQUARE CUT RINGS

SV70473 is an AS568-473 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 23.94 in (608.08 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 24.49 in (622.05 mm). In service, this quad-ring seats in a standard o-ring gland while offering improved dynamic performance.

It resists aromatic hydrocarbons, chlorinated solvents, and many acids. That behavior comes from the compound itself: Viton® (FKM) offers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Verify compatibility before use with ketones and esters or amines.

It sees regular use in automotive fuel systems, aerospace, and oil and gas.
