John Guest 12mm Pipe Insert - Pack of 10
John Guest 12mm Pipe insert - Pack of 10
These John Guest Pipe Inserts push into the end of the 12mm semi-rigid piping, to ensure a solid connection into one of the push fit pipe connectors.
Without these, there's a possibility of a pipe working loose out of a fitting, particularly with a hot water system, where the pipe is under pressure and may soften with the heat.
These are compatible with both hot and cold water systems and are compliant with drinking water.
