Transition coupling SANHA SANHA-Therm Mufa przejściowa ZWxGW 42x1½ – copper/steel pipe connection 42x1.5"

SANHA-Therm Mufa przejściowa ZWxGW 42x1½ is a transition coupling intended for connecting a 42 mm outer diameter copper pipe to a 1½" threaded steel fitting. Developed by SANHA for plumbing and heating systems, this coupling creates a mechanically robust and sealed joint between dissimilar materials, enabling secure connections between copper tubing and standard threaded components used in potable water and heating installations.

Advantages

The coupling offers a compact design that simplifies the transition between smooth-bore copper pipe and threaded steel connections, reducing the need for additional adapters. Its construction ensures reliable sealing under typical domestic and commercial water and heating pressures. The product is suitable for direct installation into pipe networks where a mixed-material connection is required, and its materials and form factor support long service life when used according to specifications.

Suitable for

• Connecting 42 mm outer-diameter copper pipes to 1½" threaded fittings
• Domestic and commercial potable water systems
• Heating circuits and radiator connections
• Plumbing installations requiring transitions between copper and steel

Key specifications

• Pipe outer diameter: 42 mm
• Thread size: 1½" (female)
• Material combination: copper to steel transition
• Application media: potable water and heating fluids
• Connection type: mechanical transition coupling for smooth pipe to threaded fitting

How to use

Prepare the copper pipe by deburring and cleaning the outer surface at the insertion point. Ensure the threaded fitting is clean and in good condition. Slide the coupling onto the pipe end and tighten the threaded connection to the specified torque for the installation, using appropriate sealing tape or sealant on the male threads if required by the system design. Verify the joint is properly seated and perform a pressure test according to local plumbing standards to confirm leak-tightness.

Usage recommendations

Use in accordance with applicable national and local plumbing and heating codes. Select compatible sealing materials for potable water systems. Do not use the coupling in applications with aggressive fluids or outside its intended temperature and pressure ranges without prior verification of material compatibility.
