Product Options



Speedfit plastic pipe inserts by John Guest provide extra support to pipework when connecting a pipe to a fitting. Ideal for hot and cold water and central heating systems, they help keep pipe ends round, minimising any loss of shape which might occur when you're cutting them. Thanks to the two additional O-ring seals, these inserts support pipework structure and facilitate a more effective seal between the outside diameter of the pipe and the O-ring.

Available in sizes from 10mm to 28mm in diameter, Superseal inserts can be used with copper pipes designed to a BS EN 1057 standard and Speedfit barrier pipes designed to a BS7291 standard. They're approved by the WRAS (Water Regulations Approval Scheme) and the BBA (British Board of Agrément), so you know they're designed to the highest requirements.
