The Primaflow DZR Adaptor is an essential component for professional plumbers and DIY enthusiasts needing to bridge the gap between 15mm poly pipe systems and 25mm plumbing fittings. Engineered for longevity, this adaptor delivers a robust, leak-free connection, though users must ensure their existing pipework is properly prepared and free of debris to guarantee a secure fit.

Yes, the DZR brass construction is suitable for both hot and cold water plumbing, including central heating applications.
While these are designed for secure, long-term connections, they can typically be disconnected with the proper release tool, though it is always recommended to inspect the internal seal before reusing.
For the push-fit side, no sealant is required. If the 25mm side features a threaded connection, follow standard thread sealing protocols for that specific fitting.
DZR stands for Dezincification Resistant. It is a type of brass alloy treated to resist the leaching of zinc, which prevents the material from becoming brittle and porous over time.
This adaptor is specifically designed for 15mm poly pipe. Check your pipe specifications before installing with metal pipework.
Remove the pipe and inspect for burrs or scratches. Ensure the pipe was pushed in fully to the internal stop and that the pipe end is cut perfectly square.
Check that the pipe diameter is exactly 15mm. If the pipe end is deformed, re-cut it cleanly with a proper pipe cutter.
To install, ensure the 15mm pipe is cut square and is free from burrs, scratches, or debris. Push the pipe firmly into the 15mm end of the adaptor until it seats correctly. The 25mm end should be tightened onto the corresponding fitting according to standard plumbing practices. While the DZR brass is resistant to dezincification, avoid using harsh chemical cleaners on the exterior of the fitting. Periodically inspect the joint during routine maintenance to ensure there are no signs of moisture, which may indicate a failure to seat the pipe fully during the initial setup.
