-442 BROWN FKM 75D O-RING

APG stocks the VB75442, an AS568-442 brown Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 7.225 in (183.52 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.775 in (197.49 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists many acids, aromatic hydrocarbons, and chlorinated solvents. Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. Published continuous service range is -15°F (-26.1°C) to 400°F (204.4°C). It should not be specified for service in low-molecular-weight organic acids or ketones and esters.

Typical settings include chemical processing, high-temperature process equipment, and aerospace.

VB75442 ships individually. Unit weight is approximately 46.694 g. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
