Transition nipple, male thread, 15x3/8 brass B Press P4243G01503000

Transition nipple for copper and steel installations

This bronze transition nipple, designed for the B Press crimping systems, allows you to connect a 15 mm diameter pipe with a 3/8 inch external thread. It is a key element in water, heating and gas installations where a precise and durable connection of different components is required. Made of high-quality CuSn5Zn5Pb2-C bronze, it provides corrosion resistance and long-term reliability.

Design and application

The nipple is designed to work with copper pipes (according to PN-EN 1057) and stainless steel pipes (according to PN-EN 10312). Its design based on the B Press crimping technology guarantees the tightness and strength of the connection. The tapered BSPT-R external thread (ISO 7-1 / EN 10226-1) allows for easy connection to other installation elements with the appropriate internal thread. The presence of a support collar further increases the stability of the connection.

The nipple finds application in:

• Water installations – connecting fragments of pipes with different diameters or materials.
• Central heating installations – connecting valves, pumps or other heating devices.
• Gas installations – creating safe and tight connections (in accordance with applicable standards).
• Modernization of existing installations – adapting older systems to new components.

Key features and benefits

• Durability and reliability: Made of high-purity CuSn5Zn5Pb2-C bronze, resistant to corrosion and mechanical damage.
• Tightness: The B Press crimping technology guarantees a tight connection without the need for additional sealants (although it has an EPDM gasket).
• Versatility: Possibility of connecting copper and stainless steel pipes.
• Safety: The bronze used has a reduced content of lead and nickel, allowing its use in drinking water installations (has PZH approval).
• Easy installation: The B Press crimping system significantly speeds up the installation process compared to traditional connection methods.
• Pressure resistance: The maximum working pressure is 16 bar at 20°C, which ensures safe operation in most typical installations.
• Length: Compact dimensions (39 mm) make it easy to install in tight spaces.
