568-049 FKM 75 SQUARE CUT RINGS

Part number SV70049 is an AS568-049 black Viton® (FKM) 70 Shore A square profile Quad-Ring supplied with an inside diameter of 4.989 in (126.72 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 5.129 in (130.28 mm). A quad-ring provides a dual sealing band on each contact face for improved reliability.

The compound resists chlorinated solvents, engine and transmission fluids, and aromatic hydrocarbons. That behavior comes from the compound itself: Viton® (FKM) is known for the industry benchmark where nitrile reaches its thermal limit and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in semiconductor equipment, chemical processing, and automotive fuel systems.

SV70049 ships individually. Nominal inside diameter is listed as 5 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
