SANHA reducing nipple Therm Nypel redukcyjny ZWxZZ 22ax18, copper fitting

SANHA Therm Nypel redukcyjny ZWxZZ 22ax18, a copper reducing nipple, provides a compact metal transition between 22 mm and 18 mm copper pipes. Designed for plumbing and heating systems, this copper fitting creates a secure joint where a reduction in diameter is required. The fitting is intended for use in potable water installations, heating circuits and general plumbing tasks that demand corrosion-resistant, conductive metal connections.

Advantages

The copper construction ensures good thermal conductivity and corrosion resistance appropriate for water and heating applications. Its reducing profile allows a straightforward, space-efficient connection between two different pipe sizes without the need for additional adapters. The product is manufactured to fit standard copper tubing dimensions and delivers a durable mechanical joint when installed according to common joining methods for copper fittings.

Suitable for

• Potable water distribution and domestic plumbing
• Heating systems and radiator connections
• Repairs and retrofitting where a reduction from 22 mm to 18 mm is required
• General copper pipe installations in residential and commercial buildings

Key specifications

• Material: copper
• Connection type: reducing nipple (22 mm to 18 mm)
• Application: potable water, heating circuits, general plumbing
• Shape: straight reducing coupler
• Suitable for standard copper tubing dimensions

How to use

Prepare the copper pipes by cutting squarely and removing burrs. Fit the reducing nipple onto the 22 mm and 18 mm pipe ends using the appropriate joining method for copper fittings (soldering/soft-solder, brazing or press-fit depending on the specific SANHA product family and installation practice). Ensure correct alignment and adequate clearance for heating. After joining, visually inspect the joints and perform a pressure test according to local regulations to verify leak-tightness.

Usage recommendations

Use compatible joining materials and follow manufacturer guidance for the chosen joining method. For potable water systems, ensure cleanliness of pipe ends and avoid flux or solder contamination. Confirm that operating temperatures and pressures of the system are within the limits for copper fittings and local codes before commissioning.
