568-474 FKM 75 SQUARE CUT RINGS

SV70474 is an AS568-474 black Viton® (FKM) 70 Shore A Square-Cut Ring measuring an inside diameter of 24.94 in (633.48 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 25.49 in (647.45 mm). In service, this square-cut ring provides an economical lathe-cut alternative where a moulded o-ring is not required.

This material stands up to chlorinated solvents, aggressive chemicals, and petroleum oils and fuels. Viton® (FKM) is widely chosen for very low compression set at elevated temperature and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). It is not the right choice where low-molecular-weight organic acids or ketones and esters are present. The profile itself contributes simple lathe-cut manufacture at low tooling cost and a rectangular section that will not roll in the groove. 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 oil and gas, high-temperature process equipment, and aerospace.

Stocked as SV70474 and sold individually. Nominal inside diameter is listed as 25 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation.
