Copper-reduced coupling SANHA-THERM C-Stahl 54×35 mm SANHA

SANHA-THERM C-Stahl 54×35 mm reducing coupling is a metal pipe fitting designed to connect a 54 mm pipe to a 35 mm pipe, providing a secure, pressure-capable transition between different diameters in heating and plumbing systems. Manufactured for use with C-Steel (C-Stahl) pipework, the coupling supports reliable flow adaptation, routine repairs and system modifications where a reduction in diameter is required. The fitting is intended for applications that demand mechanical strength and compatibility with common installation methods used in professional building services.

Advantages

The SANHA-THERM C-Stahl reducing coupling offers a robust metallic construction that ensures mechanical durability and stable joint integrity under typical heating system pressures. Its dimensional accuracy provides a precise fit between 54 mm and 35 mm pipes, minimising the risk of leaks when installed correctly. The design supports standard joining techniques used with C-Stahl components and helps maintain consistent flow characteristics at the reduction point.

Suitable for

• Heating system pipework requiring a reduction from 54 mm to 35 mm
• Plumbing installations using C-Stahl fittings
• Repair or retrofit work on metal pipe networks
• Commercial and residential mechanical services where durable metal couplings are specified

Key specifications

• Type: reducing coupling for metal pipe systems
• Material family: C-Steel (C-Stahl) compatible metal construction
• Connection sizes: inlet 54 mm, outlet 35 mm
• Application area: heating and plumbing installations

How to use

Prepare the pipe ends by cutting squarely and removing burrs, then clean the mating surfaces to ensure proper contact. Position the coupling onto the larger pipe end and then align the smaller pipe before completing the joint according to the chosen joining method for C-Stahl fittings (mechanical joining or soldering/welding where applicable). Follow system pressure and temperature requirements during installation and perform a pressure test after assembly to verify joint integrity.

Usage recommendations

Use the coupling only with compatible C-Stahl pipe materials and ensure installers follow local codes and manufacturer guidelines for joining methods, pressure testing and corrosion protection measures.
