SANHA reducing fitting, SANHA-Therm nipple 35 x 22 mm

SANHA-Therm reducing nipple 35 x 22 mm is a metal reducing fitting designed for joining pipes of different diameters in sanitary and heating systems. It provides a threaded connection that transitions from a 35 mm pipe to a 22 mm pipe, enabling reliable coupling between components with metric sizes. The fitting is intended for use in domestic and commercial plumbing, heating circuits, and radiator connections where a robust metal thread and reduced diameter are required.

Advantages

This reducing fitting offers a compact, durable metal construction that withstands the mechanical stresses typical of heating and sanitary installations. The threaded design ensures secure, leak-resistant connections when installed correctly with appropriate sealing materials. Compatibility with common metric SANHA systems and standard fittings simplifies integration into existing piping layouts and reduces the need for adapters.

Suitable for (tasks / use cases)

• Connecting a 35 mm supply pipe to a 22 mm radiator or branch
• Reducing pipe diameter within domestic heating circuits
• Plumbing installations requiring a metal threaded transition between sizes
• Repair or modification of commercial sanitary and heating systems

Key specifications

• Material: metal construction suitable for heating and sanitary use
• Connection type: threaded reducing nipple
• Primary pipe diameter: 35 mm
• Reduced pipe diameter: 22 mm
• Application environment: domestic and commercial heating and plumbing systems

How to use

Prepare the mating threads by cleaning and, if required, applying suitable thread sealant or tape compatible with heating and potable water systems. Screw the reducing nipple into the corresponding 35 mm threaded socket and then attach the 22 mm pipe or fitting onto the reduced end, ensuring proper alignment. Tighten to the manufacturer's recommended torque or until a secure, leak-free connection is achieved. After installation, pressurize the system and inspect for leaks following standard commissioning procedures.

Usage recommendations

Use thread sealants or PTFE tape rated for potable water and heating applications. Verify material compatibility with the system medium and operating temperatures before installation. For best results, follow applicable installation standards and local plumbing codes.
