## Long description

SANHA transition coupling Purapress ZW x GW 28 mm x 1" is a press-fit plumbing fitting designed to connect a 28 mm copper or compatible press tube to a 1" threaded pipe. The coupling is made to work with the SANHA Purapress press system and provides a compact solution for transitioning between press and threaded connections in potable water and heating installations. The product is intended for fixed installations where a reliable, leak-resistant joint is required and where compatibility with Purapress tools and press jaws is necessary.
Advantages
The transition coupling enables a secure press connection on the tube side combined with a threaded connection on the pipe side, reducing installation time compared with traditional soldering. Its design is suitable for potable water and heating systems, offering corrosion-resistant materials and a profile compatible with standard press fittings. The coupling produces a consistent, repeatable joint when used with approved press tools and the correct press jaws.
Suitable for
Connecting 28 mm press tubes to 1" threaded pipes in potable water systems
Linking press-installation piping to existing threaded heating components
Retrofit and repair work where a transition between press and threaded connections is needed
Key specifications
Connection types: 28 mm press (Purapress) to 1" female/male threaded
Intended media: potable water and heating fluids
Material characteristics: corrosion-resistant metal suitable for domestic plumbing
Compatibility: designed for use with SANHA Purapress press tools and compatible press jaws
Application: fixed, permanent installation for pressure-bearing systems
How to use
Prepare the 28 mm tube by cutting square and deburring the end. Ensure the 1" threaded pipe is clean and properly sealed using an appropriate thread sealant or tape if required by the installation practice. Slide the coupling onto the tube and position the press joint according to SANHA Purapress instructions. Use the correct Purapress pressing tool and jaws for 28 mm to perform the press operation until a full press cycle is completed. After pressing, verify the integrity of the threaded connection and perform a pressure test of the installation in accordance with applicable standards.
Usage recommendations
Use only approved Purapress tools and jaws, follow SANHA installation guidelines, and perform pressure testing after installation. Do not use the coupling in applications with aggressive chemicals or media for which the material is not rated.
