Bronze coupling 4270G 54x2" LWxGW 4270G054016000

Description and application

Coupling 4270G054016000 54 × 2" LWxGW is a component that connects two sections of a gas installation with a diameter of 2 inches (50 mm). One side has a soldering hole, allowing a permanent joint with steel or copper pipe, while the other side is equipped with an internal BSPP‑G cylindrical thread (ISO 228‑1) – standard in gas networks. Thanks to its simple shape and 180° arc angle, the coupling is ideal for straight line sections where a reliable and tight joint is required.

Key features and benefits

• Bronze material CuSn5Zn5Pb2‑C – provides corrosion resistance and good mechanical strength while remaining easy to machine.

• Soldered connection – enables quick installation without the need for special tools; perfect for installers who value time efficiency.

• BSPP‑G thread – compatible with most gas fittings on the market, simplifying the selection of complementary components.

• Outer diameter 54 mm – ensures connection stability and minimizes the risk of displacement under pressure.

• Simple shape, 180° arc angle – facilitates fitting to existing pipes and reduces the need for additional straightening elements.

• Weight 0.37 kg – lightweight construction does not overly load the substrate or mounting brackets.

Installation and compliance with standards

The coupling meets the requirements of standard PN EN 1982, guaranteeing its suitability for installations that comply with European safety standards. Installation consists of:

1. Preparing pipe ends – clean the surface and match the 2 inch diameter.

2. Soldering the joint – using the appropriate bronze soldering technique ensures durability and tightness.

3. Threading the BSPP‑G – manually or with a socket wrench until uniform compression is achieved.

Thanks to this design, the coupling is not only practical for professional installers, but also gives the end user confidence in long‑term, trouble‑free operation of the gas installation.
