3.5MM CS X 34.7MM ID BLACK FKM 75D

Ordered as V3.5X34.7, this is a black Viton® (FKM) 75 Shore A O-Ring with an inside diameter of 34.7 mm (1.366 in), a cross section of 3.5 mm (0.138 in), and an outside diameter of 41.7 mm (1.64 in). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load. Additional detail on this item: Metric O-RING, JIS P35.

The material holds up against petroleum oils and fuels, many acids, and chlorinated solvents. That behavior comes from the compound itself: Viton® (FKM) delivers the industry benchmark where nitrile reaches its thermal limit 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). It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

Maintenance and OEM teams specify it across high-temperature process equipment, chemical processing, and aerospace.

Stocked as V3.5X34.7 and sold individually. Unit weight is approximately 2.1241 g. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
