Dixon Valve Coupling 250-D-AL Cam Groove Coupling 2.5in

Product Description

The DIXON VALVE COUPLING 250-D-AL is a Part D cam and groove coupling designed for quick-connect fluid transfer applications. Built from aluminum, this female coupler features FNPT (female national pipe thread) threading and handles pressures up to 150 psi. At 2.5 inches, it falls into the larger end of standard cam-and-groove sizing, making it well-suited for high-volume liquid or dry-bulk transfer lines. Licensed plumbers, industrial maintenance technicians, and fleet service crews regularly install this type of fitting in agricultural, chemical, petroleum, and general industrial piping systems.

This coupling is used in applications where fast, tool-free connect and disconnect of hose lines is required. Part D designates a female coupler with FNPT thread, allowing it to mate with a standard male NPT pipe end or adapter. Typical install scenarios include tank truck transfer lines, irrigation manifolds, petroleum dispensing equipment, and industrial process piping where 2.5-inch flow capacity and a reliable 150 psi pressure rating are required.

Key Features

• Part D cam and groove configuration: female coupler with FNPT thread for fast hose connection
• Aluminum construction offers corrosion resistance and reduced weight compared to steel alternatives
• 150 psi maximum working pressure rating
• 2.5-inch thread size accommodates high-flow transfer applications
• Sold individually, no minimum quantity required beyond single-unit purchase

Compatibility

Designed as an OEM-style replacement or new-installation cam and groove female coupler for 2.5-inch NPT-threaded pipe connections in industrial, agricultural, and fluid-transfer piping systems.

Installation Notes

Installation should be performed by a qualified plumber or industrial piping technician familiar with cam and groove fittings and NPT thread standards. Shut off and depressurize the line completely before removing or installing any coupling. Apply appropriate thread sealant to the FNPT connection per system and fluid compatibility requirements. Verify that working pressure does not exceed the 150 psi rated maximum and that the mating cam and groove adapter is the correct Part D counterpart.
