Cpc Colder Products MCD1004 Quick Disconnect Coupling

Product Description

The CPC COLDER PRODUCTS MCD1004 is a valved quick disconnect coupling body designed for fast, tool-free fluid line connections in industrial and trade applications. Constructed from brass with a chrome-plated finish, this coupling body accepts a 1/4 NPT thread connection and includes an internal valve that stops flow when the coupling is disconnected. It measures 1.08 inches overall length by 0.63 inches overall height and handles pressures up to 250 psi across a temperature range of -40 to 180 degrees F. Plumbers, HVAC technicians, and industrial service professionals install this type of fitting where repeated connect-disconnect cycles are required without fluid spillage.

This coupling body is suited for residential and light commercial fluid systems where quick disconnects are needed for maintenance access, equipment swaps, or modular plumbing configurations. The 1/4 NPT thread makes it compatible with standard pipe fittings found in hydronic systems, compressed air lines, coolant loops, and similar low-to-medium pressure fluid circuits. Its compact footprint allows installation in tight service areas.

Key Features

• Valved body stops flow automatically when coupling is separated, reducing fluid loss
• 1/4 NPT thread for compatibility with standard pipe fittings
• Brass construction with chrome-plated finish for corrosion resistance
• Rated to 250 psi maximum working pressure
• Wide operating temperature range: -40 to 180 degrees F
• Compact size: 1.08 inches OAL x 0.63 inches overall height

Compatibility

Designed as an OEM-style quick disconnect coupling body in the MC Series, compatible with standard 1/4 NPT fittings and mating MC Series coupling inserts. Specific system compatibility should be verified against the installed mating half and application requirements.

Installation Notes

Installation should be performed by a licensed plumber or qualified trade professional. Shut off system pressure and depressurize the line completely before threading in or removing any fitting. Apply thread sealant or PTFE tape to NPT threads per IPC guidelines and torque by hand to start, then wrench-tighten without over-torquing to avoid cracking the body. Verify there are no leaks at the connection before returning the system to service.
