The 1″ Nut x 22mm Adaptor for 22mm Copper provides a highly efficient way to connect primary rigid copper supply lines straight to underfloor heating components. Installers primarily use this transitional fitting to bridge 22mm copper pipework onto 1″ manifold header bars, primary mixing valves, or boiler circulating pumps. Consequently, the streamlined mechanical design ensures a perfectly secure, non-restrictive fluid crossover point between different plumbing materials. Furthermore, the premium brass and copper assembly delivers outstanding structural integrity capable of handling high temperature and operational pressure variations. The free-spinning 1″ coupling nut allows for easy, flush tightening without forcing you to twist or stress the pre-installed copper line. Additionally, the flat-faced sealing surface ensures a clean, leak-proof joint when combined with a standard rubber or fibre washer. Therefore, you can complete primary mechanical hookups quickly while guaranteeing continuous flow performance for the long term.
  • Streamlined Crossover Transition: Precision-engineered to link 22mm copper tubes straight to 1″ threaded equipment. Consequently, it eliminates the need for messy multi-fitting adapters or bulky reductions.
  • Free-Spinning Captive Union Nut: Features an independent 1″ swivel nut that tightens smoothly against the manifold thread. Therefore, you can easily secure the joint within confined utility cupboards or tight wall clearances.
  • Flat-Face Mechanical Sealing: Designed with a precision-machined flat face to host a matching sealing washer or gasket. As a result, the fitting provides absolute protection against long-term localised weeping or pressure leaks.
  • Heavy-Duty Construction Profile: Manufactured using robust, high-grade metal alloys to resist corrosion and chemical degradation. Additionally, this premium construction safely absorbs continuous system thermal expansion cycles.
  • Unrestricted Flow Capabilities: The smooth interior bore matches the natural dynamics of 22mm copper systems. Subsequently, the streamlined path prevents unexpected flow bottlenecks and helps maximise overall circulating pump efficiency.
