Details

The John Guest Speedfit NC471 provides a specialized solution for bridging modern metric systems and legacy imperial pipework. This adaptor connects 15mm copper or plastic pipe to 5/8″ imperial tubing with total reliability. Speedfit’s signature push-fit technology allows you to create a secure, flame-free joint in seconds without any specialist plumbing tools. It performs excellently in hot and cold water services as well as central heating systems. Consequently, this connector ensures a professional, leak-proof transition when modernizing older plumbing installations.

Modernizing older heating or water systems often uncovers a frustrating sizing mismatch. Specifically, 15mm and 5/8″ pipes appear interchangeable at a glance, but a standard 15mm fitting cannot seal correctly on a 5/8″ pipe. Attempting to use the wrong connector frequently leads to persistent drips or sudden joint failure once the system reaches full pressure. Furthermore, finding specialized transition fittings in local hardware stores often proves difficult, forcing many to rely on unreliable “close-enough” workarounds. However, the Speedfit NC471 Adaptor solves these issues. Its internal engineering specifically accounts for the subtle diameter difference between the two standards, gripping both pipes firmly. You simply push the fitting onto the pipe ends to secure a permanent, professional-grade seal. Therefore, you eliminate the risk of leaks and the hassle of soldering when working with legacy 5/8″ pipework.
