Sorry guys not thinking straight atm, I've got a sickness bug
I was thinking about using some olive oil on the end of the tube when you insert it in the fittings. Can it be sunflower oil or has it got to be olive? Cheers.
You basically put as much on the insert as you need, then slide it in. I usually dips my fingers in a little dish I've poured it in to, then run up and down the insert a bit. Not to the point where it's dripping off or anything, but just so it covers a fair portion of it.
I don't know about sunflower... maybe. You shouldn't have that anyway, you realise how bad that is for you?! Put that in the bin and get some decent extra virgin olive oil instead. But don't cook with it... cook with coconut oil, much better.
Don't do that you'll get it in the loop... get a pipe reamer on Amazon for about £4 and use that to create the angled edge. Sand smooth if you want, use distilled water to lubricate if you need but shouldn't have a problem pushing it in with the finished edge.
No you won't! Just rinse the tubes out with a bit of washing liquid and water a few times, then final rinse with water until clear. Works a treat. Done this loads of time, no trace of oil left.
