Brass compression burst pipe repair coupling / connector, for fixing leaks in 15mm pipe. Allows you to cut / bypass damaged pipe section.
One side is similar to a slip coupler so only a small piece of pipe needs to be cut to slide this fitting into position.
Compression plumbing fittings do not require heat or solder. The joint is formed by tightening a nut and compressing the olive (included with fitting) onto a copper or plastic pipe, which forms the seal. They can be used on wet pipework, and are suitable for hot and cold systems.
