568-204 FKM 75 SQUARE CUT RINGS

This quad-ring is supplied in AS568-204 black Viton® (FKM) 70 Shore A square profile supplied with an inside diameter of 0.359 in (9.12 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.637 in (16.18 mm), catalogued under part number SV70204. It seats in a standard o-ring gland while offering improved dynamic performance.

The material holds up against engine and transmission fluids, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for outstanding high-temperature capability and very low compression set at elevated temperature. 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 low-molecular-weight organic acids.

You will find this material specified across semiconductor equipment, high-temperature process equipment, and oil and gas.

SV70204 ships individually. Nominal inside diameter is listed as 3/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
