Ordered as V5X78, this is a black Viton® (FKM) 75 Shore A O-Ring supplied with an inside diameter of 78 mm (3.071 in), a cross section of 5 mm (0.197 in), and an outside diameter of 88 mm (3.46 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Viton® (FKM) is specified here for outstanding high-temperature capability and industry benchmark where nitrile reaches its thermal limit. The compound resists chlorinated solvents, petroleum oils and fuels, and many acids. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C). Exposure to amines or low-molecular-weight organic acids will shorten service life.
You will find this material specified across semiconductor equipment, chemical processing, and high-temperature process equipment.
Order part number V5X78, sold individually. Unit weight is approximately 9.2257 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.
