568-150 FKM 75 SQUARE CUT RINGS

Ordered as SV70150, this is an AS568-150 black Viton® (FKM) 70 Shore A Square-Cut Ring with an inside diameter of 2.862 in (72.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.068 in (77.93 mm). The square-cut ring provides an economical lathe-cut alternative where a moulded o-ring is not required.

The compound resists aggressive chemicals, aromatic hydrocarbons, and engine and transmission fluids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for excellent resistance to compression set and permeation, 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 a flat contact band that spreads sealing load across a wider area 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.

Common environments for this compound include oil and gas, high-temperature process equipment, and automotive fuel systems.
