ODSUPPLIES - Bag of 2-15mm x 1/2" Imperial Solder Ring Coupling Available in 15mm, 22mm, 28mm, 1/2 inch BSP, 3/4 and 1 BSP

This listing is for a Pack of 2. Please note that imperial plumbing pipe is measured using traditional bore diameter therefore the pipe for this 1/2 inch side of the coupling measures 15.14mm in diameter WRAS Approved A solder ring coupling is a straight fitting used to connect two copper pipes of the same diameter. Each socket features an internal groove pre-loaded with a precise amount of lead-free solder. To prepare copper pipe for solder ring fittings, cut it square, deburr the edges, clean the pipe end and fitting socket to bright metal with an abrasive pad, and apply a thin layer of flux before assembly. To solder a solder ring fitting, clean and flux the joint, assemble it, heat the copper evenly with a blowtorch until it reaches melting temperature, so capillary action draws the molten metal into the gap around the entire pipe.
