A1 heat break PTFE diameter?

Hi Guys. I bought a second hand A1 a week ago or so. It’s in good condition with only a couple of issues. The Z rods have had a treacle like grease applied which makes the Z axis sluggish when it’s cold. I will strip that grease off. With my first test print, I got a clog. So, I thought I’d start with a clean slate and ordered Capricorn tube to put a new heat break liner. I downloaded the jig to cut the liner to length.  So I stripped the hot end and removed the liner to discover It’s not the same dimensions as the Capricorn bowden tube. It’s a thinner OD plus it’s shorter than the jig I downloaded from Thingieverse. The liner is about 15.4mm long and 3.03mm diameter. Can someone tell me the correct dimensions please?  Thanks in advance!
