Rated 5 out of 5 by from Great But Cant add to previous good reviews, gives great and secure seal etc etc. One thing to note is that unlike the 'ordinary' JG inserts, these are difficult to pull out (reuse) and more importantly, they then to get detatch from the pipe inside other push fit fittings if you re-use or doing pipe adjustments; leaving the other piece tricky to reuse as the insert is stuck inside.

Rated 5 out of 5 by from Speed Fit Inserts! These are perfect to get it leak free at first attempt. Well worth the extra over the inserts that do not have the additional washers.

Rated 1 out of 5 by from Uncertain I've used these insert for years with no problems what so ever. Having bought 3 new packs recently I found the fit in the pipe has changed from a very firm push being required to now a loose fit with practically no pressure required. I have queried with screw fix and they have no feedback on similar issues. Is this the case from other users? I don't want to pipe up an extension to a heating circuit when I'm unsure of them.

Rated 5 out of 5 by from Inserts An absolute must if you are using plastic pipe. These inserts give you the extra security of additional washers.

Can I use these plastic inserts when connecting a metal compression fitting isolating valve to plastic pipe?

Asked by: gps1970
Have used them with plastic pipe and metal compression fittings with no problem. Just don't over tighten
