Dixon Valve Coupling DV-00168 Buna-n O-ring 2 Pack

Product Description

The DIXON VALVE COUPLING DV-00168 is a Buna-N O-ring designed as a sealing accessory for cam and groove couplers. Measuring 4.875 inches outer diameter, 4 inches inner diameter, and 0.25 inches in cross-section, this O-ring provides a reliable fluid-tight seal at cam and groove connection points. Buna-N (nitrile rubber) construction offers solid resistance to petroleum-based oils, fuels, and a broad range of industrial fluids. Each package contains 2 O-rings. This part is installed by plumbing technicians, industrial maintenance personnel, and fluid-handling professionals during coupler assembly or routine seal replacement.

This O-ring is used with cam and groove couplers in fluid transfer applications across industrial, agricultural, and commercial plumbing environments. It seats in the coupler body to prevent leakage at the coupling interface. Typical installations include hose-to-manifold connections, tank transfer lines, and bulk fluid handling systems where cam and groove fittings are the standard connection method. Sold in a 2-pack to support back-to-back jobs or keep a spare on hand.

Installation Notes

Installation is performed by a qualified plumbing or fluid-handling technician. Depressurize and drain the line completely before removing the existing O-ring or disassembling the coupler. Inspect the coupler groove for nicks, corrosion, or debris before seating the new O-ring. Do not use petroleum-based lubricants on Buna-N seals unless confirmed compatible with the fluid media in service.
