16mm press-fit x 1/2" BSP female coupler (female-to-female) for joining 16mm MLCP pipe to standard 1/2" BSP threaded fittings, taps, and valves – a versatile connector for kitchen, bathroom, and central heating pipework runs, and for extending or repairing existing plumbing lines without a full re-pipe. Supplied as a pack of 5 couplers, giving trade professionals and DIY plumbers enough fittings on hand for larger installations, multi-point repairs, or several separate jobs across a property without having to re-order mid-project and risk delaying the work. Each coupler comes with a stainless steel press sleeve that crimps securely onto the MLCP pipe using a standard press tool, forming a strong, corrosion-resistant mechanical joint that resists loosening under vibration and everyday handling. A built-in O-ring seal at the connection creates a tight, reliable, and long-lasting joint, helping guard against leaks and drips at every fitting under normal working pressure, so installations stay sound for years of everyday use. Heat-free press installation means no soldering, blowtorch, or naked flame is needed – simply press and go, making this coupler a quick, safe choice for plumbing, heating, and hot/cold water systems in occupied homes, offices, and commercial properties.
