New to watercooling and I've bought an entire set of EK fittings https://www.overclockers.co.uk/ek-water-blocks-ek-acf-fitting-12-16mm-black-wc-773-ek.html
Also got 2 metres of Primo tubing https://www.overclockers.co.uk/primochill-primoflex-advanced-tubing-16-11-clear-wc-107-pm.html
Problem is this seems to be extremely tight to fit over the EK barbs. Have I bought the wrong size tubing or is it normal to have to use brute force to get it on there?
If I got the wrong size what do I need to pick? Doesnt seem to be any 12/16 stuff.
