## Summary description

Transitional coupling SANHA-Therm ZWxGW 28x1 by SANHA. A metal pipe fitting designed to join pipes or components with a 28 mm OD to a 1" threaded connection. Suited for heating and plumbing systems where transition between press-fit or soldered connections and threaded components is required. Provides mechanical stability and a sealed threaded interface for valves, pumps, or radiators.

## Long description

Transitional coupling SANHA-Therm ZWxGW 28x1 by SANHA is a metal pipe fitting that connects a 28 mm outer-diameter pipe to a 1" threaded component. Designed for use in heating and plumbing systems, the coupling allows a reliable transition between press-fit or soldered pipework and threaded valves, pumps or radiators. Its construction provides mechanical stability and a sealed threaded interface suitable for potable water and central heating circuits when installed according to applicable installation rules.
Advantages
The SANHA-Therm transitional coupling combines a robust metal body with a precisely machined threaded portion to ensure a tight, leak-resistant connection. The fitting is suitable for use with common joining methods on the 28 mm side and standard 1" threaded components on the other side, reducing the need for additional adapters. Its compact form factor simplifies installation in confined spaces and supports long-term mechanical stability when tightened correctly.
Suitable for
Transitioning from 28 mm press-fit or soldered pipework to 1" threaded valves
Connecting radiators and heating circuit components with mixed connection types
Plumbing repairs and retrofits where a change from smooth pipe to threaded fittings is required
Systems carrying potable water and closed heating circuits (when installed per regulations)
Key specifications
Connection 1: 28 mm outer diameter side for press-fit or soldered joining
Connection 2: 1" (inch) female/male threaded interface for standard threaded components
Material: metal alloy suitable for plumbing and heating applications
Application: heating and plumbing systems including radiators, pumps and valves
Design: transitional coupling for joining dissimilar connection types
How to use
Prepare the pipe and threaded component surfaces according to the chosen joining method: deburr and clean the 28 mm pipe end for press-fit or soldering, and ensure thread cleanliness and appropriate sealing (for example, PTFE tape or approved sealant) on the 1" threaded side. Assemble the 28 mm side by the specified press-fit or solder technique or by soldering/brazing where applicable. Screw the coupling onto the 1" threaded component and tighten to the torque recommended by the component manufacturer to avoid over-tightening. After installation, perform a pressure test of the system to confirm leak-free operation.
Usage recommendations
Use only approved joining methods and materials for the 28 mm connection and follow local plumbing and heating codes. Select appropriate thread sealants compatible with potable water where necessary, and check for compatibility of metals to minimise corrosion risk. If uncertain, consult installation guidelines from SANHA or a qualified installer.
