SV70202 is an AS568-202 black Viton® (FKM) 70 Shore A Square-Cut Ring with an inside diameter of 0.234 in (5.94 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.512 in (13 mm). In service, this square-cut ring presents a flat rectangular section that cannot roll or twist in its groove, making it a dependable static seal.
Viton® (FKM) offers long service life in hot, chemically aggressive environments and very low compression set at elevated temperature. This material stands up to aromatic hydrocarbons, petroleum oils and fuels, and many acids. Rated temperature range runs from -15°F (-26.1°C) to 400°F (204.4°C) in continuous service. Verify compatibility before use with ketones and esters or amines. The profile itself contributes greater resistance to extrusion than a round section of the same size and a flat contact band that spreads sealing load across a wider area. 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 semiconductor equipment, automotive fuel systems, and aerospace.
Reference part number SV70202 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
