-263 BLACK FKM 75D O-RING

Ordered as V75263, this is an AS568-263 black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 7.234 in (183.74 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 7.512 in (190.8 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists aromatic hydrocarbons, chlorinated solvents, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers very low compression set at elevated temperature and long service life in hot, chemically aggressive environments. Continuous operating temperature is published at -15°F (-26.1°C) to 400°F (204.4°C). Applications involving amines or ketones and esters call for a different compound.

You will find this material specified across oil and gas, semiconductor equipment, and chemical processing.

This item is sold individually under part number V75263. Unit weight is approximately 10.6632 g. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
