JG Speedfit STS15 Plastic Pipe Insert 15mm Pack of 50
15mm speedfit pipe inserts bag
I always buy Speedfit inserts from Screwfix because they never leak and the price is the best around. The 50 bag gets used up very quickly as we use Speedfit pipework as a matter of course on our building contracts.

I have found these to be the best inserts for speedfit pipe as go in nice and tight and stay in also.

JOHN GUEST FITTINGS
Superb quality and most reliable of all plastic plumbing pipe / fittings. Inserts design provide additional security
One tip is to ensure if using fittings with copper tube that the end of the tube has no burrs and should be cut with a pipe cutter to ensure this. Reason being a rough tube end can dislodge the "o" seal resulting in a leaking joint.
I would always use JG pipe and fittings in preference to all others.
