Mr Pex 4342575 Copper Sweat Transition Fitting

Product Description

The MR PEX 4342575 is a copper sweat transition fitting designed to connect EK Eurokonus 25 PEX manifold ports to standard 3/4 inch or 1 inch copper pipe. This fitting allows plumbers and hydronic heating installers to tie PEX-based manifold systems into copper distribution lines using a solder-joint connection. It bridges the proprietary Eurokonus 25 interface with conventional copper sweat end connections, making it a practical adapter in mixed-material piping systems. The 4342575 is suited for residential and light commercial hydronic radiant heating installations where PEX manifolds interface with copper supply and return mains.

This transition fitting is used in hydronic radiant floor heating systems, baseboard heating loops, and domestic plumbing distribution layouts where a MR PEX EK Eurokonus 25 manifold feeds into 3/4 inch or 1 inch copper pipe runs. It is installed by licensed plumbers and hydronic system technicians during new construction and retrofit projects. The sweat-end design is compatible with standard copper tubing and is soldered using conventional plumbing torch and solder methods.

Key Features

• Transitions from EK Eurokonus 25 manifold port to 3/4 inch or 1 inch copper pipe
• Copper construction for reliable, corrosion-resistant sweat connections
• Solder-joint (sweat) end simplifies integration with standard copper distribution piping
• Designed for hydronic heating and plumbing manifold installations

Compatibility

Designed as an OEM-style transition fitting for MR PEX EK Eurokonus 25 manifold systems connecting to 3/4 inch or 1 inch copper sweat pipe.

Installation Notes

Installation should be performed by a licensed plumber or qualified hydronic heating technician. Shut off the system water supply and depressurize the line before soldering. Use lead-free solder and flux in compliance with local plumbing codes and IAPMO or applicable regional standards. Allow the joint to cool fully before restoring system pressure and checking for leaks.
