TECE transitional external thread nipple 20x1/2" brass

TECE transitional external thread nipple 20x1/2" brass is a compact plumbing connector designed to join a 20 mm pipe or fitting to a device with a 1/2" external thread. Manufactured from brass, the nipple provides corrosion resistance and mechanical strength required in potable water and general plumbing systems. Its transitional form factor ensures a reliable threaded connection while preserving the integrity of the 20 mm piping system.

Advantages

The brass construction offers long-term durability and resistance to corrosion and scaling in typical domestic and commercial water applications. The part provides a precise, standardized 1/2" thread interface for compatibility with common fixtures and valves, while the 20 mm connection maintains the continuity of plastic or metal pipe runs. The small, simple design makes installation straightforward and minimizes the need for additional adapters.

Suitable for

• Connecting 20 mm supply pipes to fixtures, valves or appliances with 1/2" external thread
• Plumbing repairs and retrofit works in residential properties
• Commercial water installations where a transition from 20 mm piping to 1/2" threaded components is required
• Temporary connections during system maintenance or testing

Key specifications

• Material: brass
• Connection sizes: 20 mm to 1/2" external thread
• Type: transitional external thread nipple
• Intended medium: cold and hot water supply
• Typical installation: push-fit or soldered 20 mm pipe end to threaded component (subject to local fitting method)

How to use

Select an appropriate sealing method for the 1/2" external thread (thread tape or compatible sealant) and ensure the 20 mm pipe end is prepared according to the pipe system in use (cut square, deburred, and cleaned). Engage the nipple into the receiving 1/2" female thread by hand, then tighten using an appropriate wrench until secure; avoid excessive torque that could damage threads. For the 20 mm side, complete the connection per the system type—push-fit insertion, compression fitting, or soldering—following the pipe manufacturer’s instructions and local plumbing codes.

Usage recommendations

Verify material compatibility with the existing piping and fittings, and use certified thread sealants for potable water systems where required. Inspect the connection after initial pressurization for leaks and retighten if necessary. If unsure about the correct installation method, consult a qualified plumber or follow applicable installation standards.
