SANHA Purapress transition coupling 28 mm x 1¼" – press fitting, female thread, model 1827028114

The SANHA Purapress transition coupling 28 mm x 1¼" is a press fitting with a 28 mm press end and a 1¼" female thread designed to join press pipe systems to threaded components. It provides a gas- and fluid-tight connection between copper or steel press pipes and standard threaded fittings, enabling rapid assembly in plumbing and heating installations. The fitting is compatible with Purapress press tools and sealing systems and eliminates the need for soldering when connecting to threaded parts.

Advantages

This transitional coupling offers fast, repeatable press connections that reduce installation time compared with soldering or welding. The press end creates a reliable, leak-resistant joint when used with appropriate Purapress tools and seals, and the female thread accepts standard 1¼" male threaded fittings for straightforward integration into existing systems. The metal construction provides mechanical strength and temperature resilience suitable for many plumbing and heating applications.

Suitable for

• Connecting 28 mm copper or steel press pipe systems to 1¼" threaded valves and fittings
• Plumbing installations where solder-free jointing is required
• Heating systems that require a secure transition between press and threaded components
• Repair or retrofit work where threaded equipment must be integrated with press piping

Key specifications

• Press end diameter: 28 mm
• Thread type: female 1¼" (internal thread)
• Connection method: press fitting on one end, threaded connection on the other
• Compatibility: designed for Purapress press tools and sealing inserts
• Material: metal construction suitable for plumbing and heating media

How to use

Ensure the pipe and threaded fitting are clean and free of debris. Insert the pipe into the press end to the required stop depth and position the Purapress tool over the fitting according to the tool manufacturer's instructions. Activate the press tool to form the joint, then check the threaded connection by tightening an appropriate male fitting into the 1¼" female thread using standard pipe fitting practice. After assembly, perform pressure and leak tests as required by applicable standards.

Usage recommendations

Use only compatible Purapress sealing inserts and approved press tools; verify material compatibility with the system medium and follow local regulations for plumbing and heating installations. If installing in concealed locations or systems requiring certification, ensure the installation method meets applicable codes and standards and perform appropriate testing.
