## Summary description

SANHA PRESS SOLAR transition coupling with female thread GW 28x1 (model 113270281) is a press-fit fitting designed for solar thermal and heating piping systems. The coupling provides a secure press connection on the pipe side and a female threaded connection for mating components, enabling reliable joins between press-installed tubing and threaded valves or fittings. Suitable for use in closed solar circuits and heating installations where corrosion-resistant, pressure-tight connections are required.

## Long description

The SANHA PRESS SOLAR transition coupling female thread GW 28x1 for solar piping (model 113270281) is a press-fit adapter designed for use in solar thermal and heating systems. It combines a press connection on the pipe side with a female threaded connection to allow straightforward attachment of threaded valves, gauges or other components used in closed solar circuits and heating installations. The fitting is intended to provide a corrosion-resistant, pressure-tight transition between press-joined tubing and threaded devices.
Advantages
This SANHA PRESS SOLAR transition coupling offers a reliable press joint that reduces installation time compared with traditional soldered or flanged connections, while the female thread provides compatibility with a wide range of threaded fittings and instruments. Constructed for use in solar and heating applications, the coupling is built to maintain pressure integrity in closed circuits and resist common forms of corrosion encountered in such systems.
Suitable for
 Solar thermal piping systems and closed-loop solar circuits
 Heating installations where a press-to-thread transition is needed
 Connections to threaded valves, gauges, pumps or inspection ports
 Situations requiring corrosion-resistant, pressure-tight joints
When it may not be suitable
The coupling is not intended for use as a stand-alone structural support or where mechanical loads exceed normal pipe system forces; appropriate supports and hangers should be used. It may also be unsuitable for systems that require specialized thread types or sizes other than the specified female GW 28x1 connection.
Key specifications
 Connection type: press connection to piping and female threaded connection GW 28x1
 Application: solar thermal and heating systems, closed circuits
 Material characteristics: corrosion-resistant design suitable for heating fluids
 Sealing principle: press-fit joint on pipe side with threaded seal on female side
 Intended pressure use: suitable for typical pressures in solar and heating installations
How to use
Install the coupling by preparing the pipe end according to SANHA press system guidelines: cut the pipe square, deburr and clean the outside surface. Assemble the coupling onto the pipe and perform the press operation with a compatible pressing tool and jaw for the system. After pressing, attach the mating threaded component to the female GW 28x1 connection using appropriate thread sealant or tape when required by the system design and manufacturer recommendations. Verify tightness and support the run to prevent undue stress on the joint.
What to consider before purchase
 Confirm compatibility with the pipe diameter and the SANHA press system used on site
 Ensure the female thread GW 28x1 matches the mating component's thread type and size
 Verify material suitability for the fluids and temperatures in the intended solar or heating circuit
 Check required pressing tools and jaws are available for proper installation
Usage recommendations
Follow the manufacturer's press tool specifications, use correct-sized jaws, and observe recommended installation sequences. Test the completed system according to applicable standards and local regulations before commissioning.
