568-225 FKM 75 SQUARE CUT RINGS

This quad-ring is supplied in AS568-225 black Viton® (FKM) 70 Shore A square profile measuring an inside diameter of 1.859 in (47.22 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.137 in (54.28 mm), catalogued under part number SV70225. It delivers lower friction and better sealing stability than a comparable round-section o-ring.

Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. The compound resists engine and transmission fluids, chlorinated solvents, and petroleum oils and fuels. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or amines.

Common environments for this compound include aerospace, automotive fuel systems, and semiconductor equipment.

SV70225 ships individually. Nominal inside diameter is listed as 1 7/8 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
