Wall penetration 15x1/2x3/4x30 bronze B Press P4244G01504030

Solution for Safe Pipe Passage Through Building Partitions

This component from the B Press series is a specialized elbow fitting designed to connect copper pipelines with threaded elements in locations where the installation must pass through a wall or partition. Thanks to its "wall passage" design (designation P4244G), it enables effective sealing of the wall opening, eliminating the risk of vibration transmission or mechanical damage to the pipe at the point of contact with the rigid partition. The dimensions 15x1/2x3/4x30 indicate that one side is mounted onto a copper pipe with a diameter of 15 mm (press-fit method), while the other side features a metric external thread of 1/2 inch, transitioning into an internal thread of 3/4 inch with a length of 30 mm – facilitating connection to a fitting or valve on the opposite side of the wall.

Material and Joint Durability

A key advantage of this product is the use of high-quality materials compliant with European standards. The copper part is made from Cu-DHP copper with 99.99% purity (phosphorus-deoxidized), ensuring corrosion resistance and long service life in water and heating installations. The bronze components (alloy CuSn5Zn5Pb2-C) provide adequate mechanical strength in the threaded zone. This material combination allows safe operation across a wide range of temperatures and pressures typical of modern sanitary systems. Production takes place in Spain and Poland, ensuring compliance with the rigorous quality standards of the European Union.

Application and Practical Installation

This component is invaluable during installation work where it is necessary to route a pipe through a wall without the need for additional protective sleeves or complex repair solutions. Its 90-degree elbow shape allows for a natural bend in the pipeline route as it exits the wall, often simplifying installation under taps or valves.

• Quick installation: The copper connection is made using the press-fit method (B Profile), eliminating the need for soldering in hard-to-reach areas near the wall – only an electric or manual press tool is required.
• Thread versatility: Availability of a metric external thread (M) and transition to a pipe thread (R) facilitates integration with various types of end fittings.
• Protection against damage: The 30 mm length in the threaded section ensures sufficient mounting depth, protecting the pipe from cracks resulting from mechanical stresses in the wall opening.

This fitting combines the features of a 90° elbow with a wall passage function, making it a universal connecting element between copper systems and traditional threaded fittings. The use of phosphorus-deoxidized copper and bronze alloy guarantees joint stability even under pressure fluctuations in the installation. Installation requires only standard preparation of the pipe end and the use of the appropriate B Profile pressing jaw, significantly reducing work time compared to soldered methods. It is important to ensure proper preparation of the pipe surface before pressing and to tighten the threaded part according to the recommended torque for this type of connection. This ensures the joint remains leak-free for years of system operation.
