Bronze Union – Robust Connection for Soldering Systems

This bronze union, model 2265, is a reliable component for connecting pipes with diameters of 15 mm and 3/4 inch. Manufactured from high-quality bronze, it ensures durability and corrosion resistance—essential qualities for water and heating systems. The combination of a tapered external thread (NPT) on one side and a compression sleeve on the other enables versatile use across various system configurations.

Design and Materials

The union is engineered for easy installation and long-term performance. The bronze used (CC499K) offers high mechanical strength and resistance to chemical agents present in water and heating systems. Seals made of ethylene propylene diene monomer (EPDM) rubber guarantee leak-proof connections, eliminating the risk of leakage. The one-piece construction simplifies assembly and minimizes potential failure points.

Applications and Compatibility

This union is suitable for potable water, heating, and refrigeration systems. It is compatible with both copper and steel pipes, making it a versatile solution for professionals. Its suitability for soldering systems is confirmed by DVGW GW 6 and DVGW GW 8 standards (for copper). The maximum operating pressure of 16 bar ensures safe system operation even under demanding conditions. The presence of seals enhances connection reliability and reduces the risk of leaks. The union length is 69 mm—take this into account when planning installations.
