5.7MM CS X 49.6MM ID BLACK FKM 75D

The V5.7X49.6 is a black Viton® (FKM) 75 Shore A O-Ring measuring an inside diameter of 49.6 mm (1.953 in), a cross section of 5.7 mm (0.224 in), and an outside diameter of 61 mm (2.4 in). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: Metric O-RING, JIS P50A.

It resists aggressive chemicals, chlorinated solvents, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

It sees regular use in semiconductor equipment, chemical processing, and oil and gas.

Stocked as V5.7X49.6 and sold individually. Unit weight is approximately 8.1424 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
