Is the Brass Straight Tube Connector with Hose End, Type AI 13540 suitable for both plumbing and heating systems?

Yes. The Brass Straight Tube Connector with Hose End, Type AI 13540 is suitable for both plumbing and heating systems. It securely joins copper pipes (6–14 mm external diameter) to hoses using a combined crimp-and-press assembly that ensures a tight, stable connection. Made from high-quality brass, it offers strong corrosion resistance and long-term performance under demanding conditions. Compliance with EN 1254-2 and its robust construction make it appropriate for professional plumbing, heating, and industrial applications where reliability, safety, and ease of installation are required.

Can the Brass Straight Tube Connector with Hose End, Type AI 13540 be used with different hose materials and sizes beyond the specified 6–14 mm copper pipes?

The Brass Straight Tube Connector with Hose End, Type AI 13540 is specifically designed for copper pipes with external diameters of 6–14 mm and its assembly method (crimping the ring on the pipe combined with pressing into the socket with a nut) is optimised for that material and size range. Because of this, using it with other hose materials or significantly different diameters is not recommended without verification. Different hose materials (rubber, PVC, braided hoses, PEX, etc.) have varied wall thicknesses, compressibility and chemical compatibility; the crimp/press system may not form a reliable, leak‑tight seal on those materials. Similarly, hoses with outside diameters outside 6–14 mm will not fit correctly and cannot be securely compressed by the connector as intended. Brass construction offers good corrosion resistance, but it does not compensate for mechanical or compatibility mismatches. If you need to use different hose types or sizes, consult the hose manufacturer and product technical data or contact the connector supplier to confirm compatibility or find a dedicated fitting rated for that hose material and diameter.
