Midland Industries E-DD-3040-A Type Dd Cam Groove Coupler

Product Description

The MIDLAND INDUSTRIES E-DD-3040-A is a Type DD cam and groove spool coupler designed for connecting two female cam and groove couplings in a single inline assembly. Built from aluminum, this reducer-style coupler bridges a 3-inch female end to a 4-inch female end, making it a practical solution for transitioning between hose or pipe sizes within fluid transfer systems. Type DD cam and groove fittings conform to MIL-C-27487 and TTMA dimensional standards, ensuring interchangeability across compatible cam and groove systems. This fitting is part of the Economy Series aluminum cam and groove line and is intended for installation by plumbers, fluid handling technicians, and industrial maintenance professionals.

The E-DD-3040-A is suited for use in liquid transfer applications across agricultural, industrial, chemical handling, and general fluid conveyance systems. The reducer configuration is commonly used when a hose assembly must transition from a smaller diameter line to a larger one while maintaining a female-to-female cam and groove interface. It is appropriate for both stationary and portable fluid transfer setups where aluminum construction provides adequate corrosion resistance and weight savings.

Key Features

• Type DD cam and groove spool design connects two female cam and groove couplings
• Reducer configuration bridges 3-inch and 4-inch female coupler sizes
• Aluminum construction offers corrosion resistance and reduced weight
• Economy Series build suitable for general-duty fluid transfer applications
• Conforms to standard cam and groove dimensional specifications for broad interchangeability

Compatibility

Designed as an OEM-style replacement or direct-fit component for Type DD cam and groove systems using 3-inch and 4-inch female coupler connections in standard aluminum cam and groove hose fitting assemblies.

Installation Notes

Installation should be performed by a qualified plumber or fluid handling technician familiar with cam and groove fitting assemblies. Depressurize and drain the system fully before disconnecting or installing any cam and groove components. Verify that the cam arms on mating adapters fully seat and lock around the coupler groove before pressurizing the line. Inspect the gasket seating surfaces on both female coupler ends prior to assembly to ensure a leak-free connection.
