V1.5X55 is a black Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 55 mm (2.165 in), a cross section of 1.5 mm (0.059 in), and an outside diameter of 58 mm (2.28 in). In service, this o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
It resists chlorinated solvents, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) offers the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C). Exposure to ketones and esters or low-molecular-weight organic acids will shorten service life.
You will find this material specified across semiconductor equipment, oil and gas, and automotive fuel systems.
Stocked as V1.5X55 and sold individually. Unit weight is approximately 0.5725 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.
