Bronze nipple, 4243G 54×6/4" LWxGZ 4243G054012000

Bronze nipple – practical solder‑threaded connection

This simple yet highly functional nipple combines a soldering coupling and a BSPT‑R gas tapered thread (ISO 7‑1 / EN 10226‑1). Thanks to this, in a single operation you can join a copper pipe (diameter 1 1/2 in) with a component of 54 mm outer diameter made of durable bronze CuSn5Zn5Pb2‑C. The fitting is manufactured in Poland according to PN EN 1982, guaranteeing dimensional stability and corrosion resistance in heating and sanitary installations.

Features and benefits

• Two‑stage connection – the soldering coupling provides a leak‑tight copper joint, while the BSPT‑R thread enables quick mounting of gas or water elements without additional adapters.

• High‑grade material – bronze CuSn5Zn5Pb2‑C offers good mechanical strength and resistance to water and gas, extending the service life of the whole system.

• 180° bend angle – the straight shape eliminates unnecessary pipe bends, facilitating routing and reducing pressure loss.

• Compatibility with 1 1/2 in (40) pipes – both the soldered and threaded connections match standard diameters, speeding up part selection and reducing the number of spare parts needed.

• Lightweight construction – weighing about 0.33 kg, the element is easy to handle and install even in hard‑to‑reach locations.

Application and installation guidelines

• Heating and sanitary installations – ideal for joining copper pipes with gas or water components in central heating systems, water heaters, or industrial installations.

• Installation – first solder the coupling to the copper pipe according to the recommended temperature and flux; then the BSPT‑R thread can be tightened manually or with a socket wrench, providing a fast and reliable connection.

• Leak testing – after completion, perform a pressure or vacuum test to ensure the joint is leak‑free.

Combining soldering and threading in a single element significantly simplifies installation work, reduces the number of required parts, and minimizes the risk of leaks.
