Dixon Valve g300-b-al Cam Groove Coupler 3 in Npt

Product Description

The DIXON VALVE g300-b-al is a Type B straight cam and groove coupler designed for quick-connect fluid transfer applications. The coupler features a 3-inch female cam-and-groove end on one side and a 3-inch male NPT threaded end on the other. The body is constructed from aluminum, making it well-suited for weight-sensitive installations where corrosion resistance and durability are both required. Brass handles provide reliable cam arm operation and long service life under repeated connect and disconnect cycles. This fitting is installed by plumbers, pipefitters, and industrial maintenance technicians working on liquid transfer systems, irrigation manifolds, chemical handling lines, and bulk fluid loading or unloading stations.

The g300-b-al is used in straight-run connections where a cam and groove coupling must transition to a standard NPT threaded pipe or fitting. It is appropriate for residential, commercial, and light industrial liquid transfer applications. The straight configuration keeps plumbing runs compact and aligned. This coupler is not rated for compressed air or steam service. Applications typically include water transfer, fertilizer handling, petroleum product transfer, and similar liquid service environments where cam and groove quick-connect fittings are standard practice.

Key Features

• Type B female coupler end accepts standard cam and groove adapters for fast, tool-free connection and disconnection
• 3-inch male NPT end threads directly onto compatible NPT pipe, valves, or fittings
• Aluminum body construction reduces weight while providing corrosion resistance for liquid service
• Brass cam handles deliver positive locking and durability through repeated use cycles
• Straight fitting shape maintains inline flow path with no offset or angular transition
• Not for use with compressed air or steam service

Compatibility

Designed as an OEM-style replacement or new-installation cam and groove Type B female coupler for 3-inch female cam-and-groove to 3-inch male NPT connections in liquid transfer piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and depressurize the line completely before connecting or disconnecting the coupler. Apply appropriate thread sealant to the male NPT end in accordance with IPC guidelines before threading into the mating fitting. Under no circumstances should this coupler be used in compressed air or steam service.
