Bronze threaded coupling SANHA 4270G GW 35 mm x 5/4" (model 1427035114)

SANHA 4270G bronze threaded coupling is a cylindrical muff designed to join pipes and fittings with a nominal diameter of 35 mm to a female 5/4" threaded connection. Manufactured from bronze, the coupling provides a durable metallic transition for plumbing, heating and industrial piping where corrosion resistance and compatibility with potable water are required. The part accepts a 35 mm plain pipe on one end and a 5/4" female thread on the other, enabling a secure threaded joint without soldering or welding.

Advantages

The bronze construction offers good resistance to corrosion and dezincification in potable water and heating systems, ensuring long-term mechanical integrity. Threaded assembly simplifies installation and maintenance by allowing disassembly and replacement without specialized equipment. The coupling’s compatible dimensions permit reliable mating with standard 35 mm pipes and 5/4" threaded fittings, providing a metal-to-metal connection suitable for pressurized systems.

Suitable for

• Connecting 35 mm pipe runs to 5/4" threaded fittings in domestic plumbing
• Joining components in heating circuits, including radiators and boilers
• Repair and retrofit work where bronze components are specified for potable water
• Industrial piping systems requiring corrosion-resistant threaded couplings

Key specifications

• Material: bronze
• Connection types: plain 35 mm pipe end to female 5/4" thread
• Nominal diameter: 35 mm (pipe side)
• Thread type: internal female 5/4"
• Typical applications: potable water, heating systems, industrial piping

How to use

Prepare the pipe by cutting to length, deburring and cleaning the end face. Insert the 35 mm pipe end into the coupling and secure according to the system’s requirements (mechanical fastening, sealing compound or gasket as applicable). For the threaded side, apply an appropriate thread sealant or tape to the male thread and tighten the mating fitting into the female 5/4" thread to the recommended torque for the materials involved. After assembly, pressure-test the connection according to local codes and standards before placing the system into service.

Usage recommendations

Use compatible sealing materials suitable for potable water where required. Avoid excessive torque during threaded assembly to prevent damage to threads or distortion of the coupling. Inspect threaded joints periodically for leaks or corrosion when installed in aggressive environments.
