SANHA transition nipple SANHA-Therm ZWxGZ 22x1/2 for pipe connections

SANHA transition nipple SANHA-Therm ZWxGZ 22x1/2 is a mechanical adapter designed to connect a 22 mm press or solderable pipe end to a standard 1/2" female threaded fitting. The fitting is produced for use with metric copper and multi-layer piping systems and creates a secure transition from a smooth pipe end to a threaded connection for plumbing and heating applications. The component supports hot and cold water distribution and heating circuits where a reliable pipe-to-thread interface is needed.

Advantages

The transition nipple offers a compact and durable connection that reduces the need for additional adapters. Its design enables reliable mechanical joining of press- or solder-compatible 22 mm pipe ends to 1/2" female threaded components, ensuring steady flow and leak-resistant performance when installed correctly. The fitting is suitable for use in both potable water and heating systems and simplifies repair and modification tasks by providing a standard threaded outlet.

Suitable for

• Hot and cold water distribution lines
• Central heating and radiator connections
• Plumbing repairs and service connections
• Transitions from metric 22 mm pipework to 1/2" threaded valves or fixtures

Key specifications

• Connection 1: 22 mm press- or solder-compatible pipe end
• Connection 2: 1/2" female threaded
• Material: suitable for copper and multi-layer piping systems
• Application: potable water and heating installations
• Typical operating medium: hot and cold water

How to use

Prepare the 22 mm pipe end according to the chosen joining method (pressing or soldering) and ensure the pipe is cut square and free of burrs. Insert the pipe into the 22 mm end of the transition nipple and complete the press or solder joint following the press-tool or soldering procedure. On the threaded side, apply appropriate sealing material (such as PTFE tape or thread sealant) to the male thread before tightening into the 1/2" female mating fitting. Verify alignment and torque to avoid over-tightening and inspect the completed connection for leaks under operating pressure.

Usage recommendations

Use compatible press tool jaws and fittings when performing press connections and follow applicable local standards and regulations for potable water and heating systems. Select appropriate sealing materials for threaded joints and perform pressure tests after installation to confirm leak-tight performance.
