Copper transition nipple VIEGA 22 mm x 1/2" (model 101749) for pipe connections

VIEGA copper transition nipple 22 mm x 1/2" is a precision-made copper adapter intended to connect 22 mm copper or plastic pipes to 1/2" threaded fittings. Manufactured from copper for corrosion resistance and long service life, this transition nipple provides a solid metal-to-thread joint for water supply and heating systems. The component is suitable for installations where a compact, reliable coupling is required and where compatibility with standard 1/2" threaded valves and fittings is necessary.

Advantages

The copper construction ensures good thermal conductivity and corrosion resistance, while the compact design minimizes space requirements in tight installations. The transition nipple offers consistent dimensional accuracy for a secure fit with both pipe and threaded connections. Its metal composition reduces the risk of leaks and mechanical failure compared with some non-metallic alternatives when installed correctly.

Suitable for

• Connecting 22 mm water or heating pipes to 1/2" threaded valves and fittings
• Residential plumbing repairs and new installations
• Commercial heating and water distribution systems where metal transitions are required
• Tight or confined installation spaces requiring a compact adapter

Key specifications

• Material: Copper
• Connection 1: 22 mm pipe connection
• Connection 2: 1/2" threaded connection
• Application: Water supply and heating systems
• Design: Compact transition nipple for metal-to-thread joints

How to use

Prepare the 22 mm pipe end according to the applicable installation practice: cut square, deburr and clean the pipe surface. Insert or solder the nipple into the 22 mm pipe end or attach using the appropriate method for the pipe material and system design. Hand-tighten the 1/2" threaded fitting, then complete the final tightening with appropriate tools while observing recommended torque values for the connected fitting. After installation, perform a pressure test of the system to verify the integrity of the joint and check for leaks.

Usage recommendations

Use with compatible 1/2" threaded fittings and appropriate sealing methods (such as thread tape or sealing compound where required). Ensure soldering or joining methods follow local plumbing codes and manufacturer's guidance. Verify material compatibility when connecting to dissimilar metals to reduce potential galvanic corrosion.
