A couple years back I bough the fittings from Premacon along with the 3mm OD tubing they sell. Two weeks ago I put all the fittings on. I replaced the Leimbach tubing with the stiffer Premacon tubing. I have the pressure set to 20+Bar.
I should have measured all the seals while I had the pistons apart, something to do for later. Here's a picture.
