John Guest Speedfit 12mm Pipe Inserts

These inserts, sold in packs of 10-100, are designed for push-fit connections to 12mm O/Dia semi-rigid water pipe. When connecting Speedfit pipe to a Speedfit push-fit fitting or a compression fitting, always use a JG Speedfit pipe insert. These inserts provide crucial support to the pipework, keeping the ends of the pipe round and minimizing any loss of shape from cutting. Suitable for both hot and cold pipework.
