Copper Alloy Male Adapter SANHA 4243G GZ 15 mm x 3/4" (142431534)

SANHA 4243G copper-alloy male adapter GZ 15 mm x 3/4" is a bronze transition fitting designed to connect 15 mm tube or piping to a 3/4" external threaded fitting. Manufactured from copper alloy, this adapter provides a corrosion-resistant threaded connection for plumbing and heating systems where a reliable metal-to-thread transition is required. The compact design supports standard installation in residential and light commercial pipework.

Advantages

The copper-alloy construction ensures good corrosion resistance and mechanical strength compared with plain brass in many installations. Its external thread allows straightforward assembly to corresponding threaded fittings, reducing the need for additional transitional components. The adapter's geometry and dimensions match common 15 mm tubing, enabling secure joints with standard compression or soldering techniques used in plumbing and heating work.

Suitable for

• Connecting 15 mm copper or copper-alloy tube to 3/4" threaded valves and fittings
• Domestic and light commercial potable water distribution
• Heating system pipework where a threaded transition is required
• Repair and retrofit applications in existing pipe systems

Key specifications

• Material: copper alloy (bronze)
• Connection A: 15 mm tube-compatible end
• Connection B: 3/4" external (male) thread
• Application: plumbing and heating installations
• Corrosion resistance: improved compared to unalloyed materials
• Suitable for potable water and central heating systems (follow local regulations)

How to use

Select the adapter and mating fitting with compatible dimensions and thread type. Prepare the 15 mm tube by cutting square and deburring the end. Assemble according to the chosen joining method for the tube end (compression, soldering or press depending on system compatibility) and screw the male thread into the corresponding female threaded fitting using appropriate sealing method for the thread (e.g., thread sealant tape or liquid sealant where permitted). Tighten to recommended torque for the mating fittings and check for leaks under operating pressure.

Usage recommendations

Ensure compatibility with system materials and media; follow local plumbing codes and manufacturer guidance for potable water and heating systems. Use appropriate thread sealants and avoid over-tightening to prevent thread damage. Inspect connections after initial pressurization and during periodic maintenance.
