Product information
The BONFIX Alu-press brass press coupling socket tapering to push-fit 20 x 22 is used to connect a 20 mm Alu-press multilayer pipe to a 22 mm push-fit connection. This coupling is ideal for the renovation and modification of existing installations where push-fit piping is retained and combined with new multilayer piping. The press side ensures a secure and leak-free connection to the multilayer pipe, while the push-fit side enables a quick and practical connection to existing piping. Suitable for drinking water and central heating systems.

Broad compatibility with press jaws, clear size coding, and high material quality ensure efficient and error-free work. BONFIX Alu-press complies with applicable standards and is suitable for professional use in both new construction and renovation.
