Copper nipple, 5243 35Ax18 LZxLW 5243 035018000

Connecting copper pipes 35 mm ↔ 18 mm – simple and reliable method

The copper sleeve from series 5000 enables a quick connection of a pipe with an outer diameter of 35 mm to a smaller pipe DN 18 (≈ 18 mm) using traditional soldering. Thanks to its simple shape and a full 180° arc, the element provides even heat distribution, facilitating a durable and leak‑tight joint in both water and heating installations.

Applications and practical benefits

• Fast installation – a short soldering end and a sleeve for soldering allow simultaneous heating of both ends, reducing the installer’s work time.

• Versatility – ideal for residential systems and small commercial facilities where connecting pipes of different diameters is required.

• Joint durability – the full arc angle eliminates concentration of mechanical stresses, allowing the joint to withstand varying pressure and temperature.

• Ease of maintenance – the smooth surface of Cu‑DHP copper (purity 99.99 %) ensures even heat distribution and minimizes the risk of deposits or corrosion.

Technical specifications and compliance

The element is made of deoxidized phosphorus copper Cu‑DHP, guaranteeing high thermal conductivity and resistance to water and chemical agents. The product complies with the requirements of standard PN EN 1254, and its production takes place in Spain and Poland – ensuring quality control at every stage. The simple shape and 180° arc angle make the sleeve fit perfectly with standard soldering methods used in the installation industry.

With this sleeve you achieve a reliable joint without the need for additional adaptive components – a simple solution that works in practice.
