Bronze nipple, 4243G 15x1/2" LWxGZ 4243G015004000

Simple bronze nipple for soldering and threading

Made of bronze CuSn5Zn5Pb2-C (CC499K-DW) according to PN EN 1982, this element connects a copper installation with a threaded system without the need for additional adapters or reducers. The soldering coupling allows a durable, leak‑tight connection with a copper pipe of 15 mm diameter, and the external BSPT-R thread (ISO 7-1 / EN 10226-1) ensures compatibility with standard valves, heaters or gas fittings.

The 180° angle makes the nipple act as a straight transition – ideal where a simple change of connection type without an angle is required. There are no complicated shapes or extra parts – just a clean, proven connection between two systems.

The material – bronze – not only provides corrosion resistance in water and gas installations but also responds well to soldering. It does not need to be ground before installation, nor does it require special pastes – standard hard‑soldering technique is sufficient. The thread is precisely made and does not require additional sealing with tape – proper tightening torque is enough.

The product is made in Poland and complies with standards for materials in contact with drinking water and gas. There are no plastic inserts or coatings – everything is homogeneous metal and intended for pressure service. Weight is about 20 g, minimal size – it does not occupy space in gaps between walls or under floors.

For the installer: easy to install, requires no special equipment beyond a soldering iron and a thread wrench. For the user: it does not risk leaks when changing equipment – the thread is standard and proven.
