Bronze coupling 4270G 28x1/2" LWxGW 4270G028004000

Universal soldered and threaded connection

Enables quick and durable joining of copper pipes with a diameter of 1/2 inch (15 mm) to a gas installation equipped with an internal BSPP‑G thread. Thanks to its simple shape and a full 180 ° bend, the element maintains a linear pipe run, facilitating installation in both new systems and retrofits of existing networks.

Key benefits

• Bronze material CuSn5Zn5Pb2‑C – corrosion‑resistant and tolerant to atmospheric factors, extending the service life of the joint.
• Soldered connection – provides leak‑tightness in copper installations without the need for additional sealants.
• BSPP‑G internal gas thread (ISO 228‑1) – compatible with standard gas components, allowing safe connection of gas devices.
• External pipe diameter 28 mm – matches common pipe sizes used in heating and sanitary installations.
• Simple shape – eases straight‑line pipe routing, minimizing the need for additional straightening fittings.
• Compliance with PN EN 1982 – guarantees quality and conformity with European requirements for soldered fittings.

Installation and compliance

• Soldering – simply heat the joint area and apply appropriate flux; after cooling, a permanent, leak‑tight connection is achieved.
• Threading – before applying the thread, it is recommended to use PTFE tape or sealing paste to improve resistance to gas leaks.
• Operating conditions – suitable for temperatures from -20 °C to +120 °C and in high‑humidity environments.
• Country of origin – manufactured in Poland, ensuring rapid technical support and easy availability of spare parts.

This coupling provides a practical solution for professional installers who value fast assembly and reliability, as well as end users seeking long‑lasting tightness and safety for gas and water installations.
