SANHA Purapress transitional coupling 22 mm x 3/4" (male/female)

SANHA Purapress transitional coupling 22 mm x 3/4" (male/female) is a press-fit to threaded adapter intended for connecting 22 mm copper or compatible press-fit piping to 3/4" threaded fittings. The coupling combines a press connection on the 22 mm side with a threaded connection on the 3/4" side, enabling a reliable transition between press-fit tubing systems and threaded valves, fixtures or adapters used in plumbing and heating installations.

Advantages

The coupling provides a secure, leak-resistant press-fit joint on the 22 mm piping side while offering the flexibility of a 3/4" threaded connection for compatibility with standard threaded components. Its design supports efficient installation with press tools, reduces assembly time compared with traditional soldering or welding, and maintains mechanical strength suitable for potable water and heating systems. The transitional design minimizes the need for additional adapters and simplifies system layout where pipe type or size conversion is required.

Suitable for

• Connecting 22 mm copper or compatible press-fit pipe to 3/4" threaded valves and fittings
• Domestic and commercial potable water distribution
• Heating systems where press-to-thread transitions are required
• Retrofit and repair jobs that join press-fit piping to existing threaded components

Key specifications

• Connection A: press-fit for 22 mm pipe
• Connection B: 3/4" threaded (male/female interface as specified)
• Material: corrosion-resistant metal suitable for plumbing and heating systems
• Intended application: potable water and heating installations
• Installation method: press-fit on the 22 mm side and threaded connection on the 3/4" side

How to use

Prepare the 22 mm pipe by cutting squarely and deburring the internal and external edges. Slide the appropriate Purapress sleeve over the pipe if required by the press system, insert the pipe fully into the coupling's press end, and actuate the press tool according to the tool manufacturer's instructions to form the permanent joint. On the threaded side, apply a suitable thread sealant or tape to the male threads if required for the intended application, then tighten the threaded component to the coupling to achieve a secure mechanical and fluid-tight connection. Follow local codes and pressure-temperature ratings when assembling and testing the system.

Usage recommendations

Use certified press tools and compatible Purapress sleeves when making the press connection. Verify material compatibility with system media and operating temperatures. Test the assembled system for leaks and correct operation before commissioning. For installations subject to specific regulations, follow local plumbing and heating standards and manufacturer's installation guidance.
