## Long description

SANHA THERM C-Stahl 88.9 x 54 mm pipe reduction coupler is a durable fitting designed to create a secure transition between 88.9 mm and 54 mm steel pipes in thermal and heating systems. The coupler is intended for use where a stepped diameter change is required and can be applied in threaded or press-compatible installations depending on the system components and connection method chosen. Constructed for compatibility with typical heating system materials, it supports reliable hydraulic and thermal performance in commercial and industrial piping networks.
Advantages
The reduction coupler offers a compact solution for changing pipe diameters without extensive rework of existing lines. Its steel construction ensures mechanical strength and resistance to the operational pressures and temperatures common in central heating and industrial applications. Compatibility with both threaded and press-style connections provides installation flexibility and allows the fitting to be integrated into a variety of assembly workflows. The shape and tolerances of the coupler support leak-tight joints when installed according to industry best practices.
Suitable for
Central heating systems requiring a diameter transition between 88.9 mm and 54 mm steel pipe runs
Plumbing and hot-water distribution where stepped reductions are needed
Industrial piping installations with mixed-diameter steel pipe sections
Retrofit or repair work on existing steel pipe networks
Key specifications
Material: steel suitable for thermal/heating installations
Connection style: compatible with threaded and press-type connections (installation-dependent)
Inlet diameter: 88.9 mm
Outlet diameter: 54 mm
Function: reduction coupler for stepped-diameter transitions
How to use
Select the appropriate connection method (threaded or press) compatible with the existing piping system. Prepare pipe ends by cutting square, deburring, and cleaning to ensure proper fit and sealing. Fit the coupler onto the 88.9 mm and 54 mm pipe ends, aligning carefully to maintain flow direction and avoid stress on adjacent fittings. Apply the required sealing method or press procedure according to the chosen connection type and manufacturer installation guidelines. After assembly, perform a pressure or leak test following applicable standards before placing the section into service.
Usage recommendations
Use certified installation tools and follow local regulations and SANHA installation instructions. Ensure materials in contact are compatible with steel and suitable for the operating temperature and pressure of the system. When in doubt, consult a qualified installer to confirm the correct connection technique and to perform testing after installation.
