Rated 5 out of 5 by from Pipe inserts Just used 22mm and 15mm doing bathroom remodel along with Speedfit elbows, reducers and straight connectors just so good to work with for a non plumber like myself.

Rated 5 out of 5 by from Great pipe insert! Pay the few pence more to get these super seals instead of the cheaper ones. If your doing a big job its better value to buy the bigger 100 pack, I made the mistake and bought lots of the 10 packs. You always use more than you think. Highly recommended.

Rated 5 out of 5 by from Just the job essential piece of kit for doing push fit plastic piping, easy to use, lick it, shove it in and tap it home with small hammer or similar. you don't seem to need these for inline taps though !

Rated 5 out of 5 by from Superseal inserts JG superseal inserts make JG fittings secure in the most rough conditions, as they provide a secondary seal through the twin 'O' rings so if the rest of the fitting should have any un-forseen issues, it shall still remain fluid/watertight.
