Midland Industries E-CGA-3040-A Cam Groove Reducer Adapter

Product Description

The MIDLAND INDUSTRIES E-CGA-3040-A is a Type A cam and groove reducer adapter designed for quick-connect fluid transfer applications. It features a 3-inch male cam and groove adapter on one end and a 4-inch female NPT connection on the other, allowing a size transition between incompatible hose and pipe fittings. Constructed from aluminum, this fitting is lightweight and resistant to corrosion in many fluid handling environments. The 4-8 thread specification ensures a secure threaded engagement on the female NPT end. It is suited for use by industrial maintenance technicians, plumbers, and fluid handling professionals working with cam and groove coupling systems.

This adapter is used in applications where a cam and groove hose assembly must connect to a larger female NPT port on a tank, pump, manifold, or piping system. The reducer design bridges the 3-inch to 4-inch size difference without the need for additional bushings or transition fittings. Common installation scenarios include bulk fluid transfer, agricultural irrigation systems, chemical handling, and industrial process piping where quick-disconnect hose couplings are standard practice.

Installation Notes

Installation should be performed by a qualified plumber or fluid systems technician familiar with cam and groove coupling systems and NPT threaded fittings. Depressurize and drain the line completely before removing any existing fitting or installing this adapter. Apply an appropriate thread sealant to the female NPT threads per the fluid system requirements and applicable codes. Do not overtighten the NPT connection; hand-tighten and follow standard wrench-turn guidance per IPC or system manufacturer recommendations.
