568-365 FKM 75 SQUARE CUT RINGS

The SV70365 is an AS568-365 black Viton® (FKM) 70 Shore A Square-Cut Ring supplied with an inside diameter of 6.975 in (177.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.395 in (187.83 mm). This square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.

It resists aromatic hydrocarbons, many acids, and petroleum oils and fuels. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and very low compression set at elevated temperature. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in hot water and steam or low-molecular-weight organic acids. 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.

Maintenance and OEM teams specify it across semiconductor equipment, oil and gas, and automotive fuel systems.
