Bronze nipple, 4243G 54x2" LWxGZ 4243G054016000

Brass nipple – practical soldered and threaded connection

This simple brass nipple with a 180 ° arc angle combines the two most commonly used mounting methods – soldering coupling and conical external gas thread BSPT‑R (ISO 7‑1 / EN 10226‑1). Because of this, it can be installed in both water and gas systems without the need for additional adapters. The nominal diameter is 2 inches (DN50) and the pipe outer diameter is 54 mm, providing a perfect fit for standard pipes of this size.

The bronze material CuSn5Zn5Pb2‑C (CC499K‑DW) complies with standard PN EN 1982, which translates into:

• corrosion resistance in humid and gas environments,

• high mechanical strength, essential for pressure‑bearing connections,

• ease of soldering – the coupling enables quick and durable joints using traditional soldering techniques.

Benefits for the installer and the end user

• Versatility – one end ready for soldering, the other equipped with a standard BSPT‑R thread, eliminating the need for extra fittings.

• Compliance with standards – meets European requirements for gas and water installations, simplifying technical approval.

• Polish production – quality control at every manufacturing stage guarantees dimensional repeatability and material properties.

• Easy installation – the straightforward “simple” design allows rapid fitting and reliable sealing without leak risk.

• Durability – the bronze alloy ensures long‑life performance even under harsh operating conditions.

This nipple is suitable for heating systems, sanitary installations, and gas appliance connections. The combined soldered and threaded ends make it convenient for professional fitters as well as DIY homeowners.
