Midland Industries CGF-4030-A Cam Groove Reducer Adapter

Product Description

The MIDLAND INDUSTRIES CGF-4030-A is a Type F cam and groove reducer adapter machined from aluminum. It connects a 4-inch male cam and groove adapter end to a 3-inch male NPT threaded end, making it a practical solution for reducing line size within hose and pipe assemblies. The casting is rated for a temperature range of -150 to 250 degrees F, covering most fluid transfer applications where aluminum cam and groove fittings are standard. This fitting is installed by plumbing and fluid-handling technicians working on transfer lines for water, fuel, chemical, or agricultural fluid systems.

This adapter is suited for industrial and agricultural fluid transfer systems where a reduction from a 4-inch cam and groove connection to a 3-inch NPT threaded connection is required. It is commonly used in tanker truck unloading, irrigation manifolds, and bulk fluid transfer setups where quick-connect cam and groove couplings mate to threaded pipe or valve inlets. The aluminum construction keeps weight low while providing adequate corrosion resistance for general-purpose liquids.

Key Features

• Type F cam and groove configuration with 4-inch male adapter on one end
• 3-inch male NPT thread on the opposite end for direct pipe or valve connection
• Aluminum construction offers lightweight handling and corrosion resistance
• Temperature-rated casting from -150 to 250 degrees F
• 3-8 thread specification for proper NPT engagement

Compatibility

Designed as an OEM-style replacement or retrofit fitting for cam and groove hose assemblies requiring a 4-inch to 3-inch reduction with a male NPT outlet. Consult system documentation to confirm pressure ratings and fluid compatibility before installation.

Installation Notes

Installation is typically performed by plumbers or fluid-handling technicians familiar with NPT thread engagement and cam and groove coupling standards. Shut off all fluid flow and depressurize the line before servicing any cam and groove fitting. Apply appropriate thread sealant to the male NPT end per system requirements and follow applicable plumbing codes for the fluid being transferred. Do not exceed the temperature or pressure ratings of the fitting or the hose assembly it connects to.
