Ever-tite 312DBR Cam Groove Coupling 1-1/4 in Part D Brass

Product Description

The EVER-TITE COUPLING PRODUCTS 312DBR is a 1-1/4 inch Part D cam and groove coupling designed for fast, tool-free connections in fluid transfer systems. Constructed from solid brass, it features a female coupler with FNPT thread and is rated to a maximum working pressure of 350 psi. This type of coupling is widely used in industrial, agricultural, and commercial plumbing applications where repeated connect-and-disconnect cycles are required without threaded assembly. Plumbers and fluid system technicians install this fitting when quick-connect performance is needed on hose and pipe runs handling liquids or compatible gases.

The 312DBR is suited for residential and commercial fluid transfer installations, irrigation systems, tank filling operations, chemical transfer lines, and general industrial piping. The Part D designation identifies it as a female coupler that accepts a male adapter on the mating end. The FNPT thread allows direct connection to standard NPT male-threaded pipe, fittings, or valves commonly found in plumbing and industrial setups. Its brass construction makes it appropriate for water, oil, and a range of compatible media where corrosion resistance and durability are required.

Key Features

• Part D cam and groove configuration: female coupler with FNPT thread end
• 1-1/4 inch thread size for standard NPT compatibility
• Brass construction offers corrosion resistance for water, oil, and compatible fluid service
• 350 psi maximum working pressure rated for demanding transfer applications
• Tool-free cam and groove locking mechanism enables fast connect and disconnect

Compatibility

Designed as an OEM-style replacement or direct-fit cam and groove coupling for systems using standard 1-1/4 inch FNPT Part D female coupler fittings in fluid transfer piping applications.

Installation Notes

Installation should be performed by a qualified plumber or fluid systems technician familiar with cam and groove fittings. Depressurize and drain the line completely before removing or installing any coupling. Inspect cam arms and gasket seat for wear before connecting; a worn or missing gasket is a common cause of leaks at cam groove joints. Verify that the mating male adapter is the correct Part D style and that thread engagement on the FNPT side meets applicable IPC or local plumbing code requirements before returning the system to pressure.
