7MM CS X 181MM ID BLACK FKM 70D

This o-ring is supplied in black Viton® (FKM) 70 Shore A with an inside diameter of 181 mm (7.126 in), a cross section of 7 mm (0.276 in), and an outside diameter of 195 mm (7.68 in), catalogued under part number V7X181. It provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The material holds up against chlorinated solvents, aromatic hydrocarbons, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) delivers excellent resistance to compression set and permeation, the industry benchmark where nitrile reaches its thermal limit. Service temperature is rated from -15°F (-26.1°C) through 400°F (204.4°C).

Maintenance and OEM teams specify it across automotive fuel systems, high-temperature process equipment, and semiconductor equipment.

Reference part number V7X181 when ordering; the item is sold individually. Review your operating media and conditions against this specification before installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
