if you decide to go with the Maze 3 clear top, have them install it, because you'll risk of cracking or weakening the top itself and possible future leaks

Most cracks apear sooner or later from overtightening, best thing to use is silicone sealant(as DangerDen use), aply sealant to bottom half of thread on barb, hand tighten the barbs into block, then give them a 1/4, 1/2(depending on how tight/stiff the thread feels) turn with a spanner, then leave overnight to allow the sealant time to cure.
I did my M3 with PTFE tape and hand tightened and 1/2 turned it,(I could of tightened it 3 or 4 turns) has'nt leaked since...
Some barbs have a slightly conical shape, wider at the top, these are the ones that can cause cracking the most. even normal ones may crack over time if overtightened, due to expansion/contraction with temperature fluctuation, not going too far past hand tight is the key, plus sealant does'nt depend on tightness/compression for its seal...
If you're really worried get some plastic/nylon barbs, they usualy have a wider inner bore compared to most brass ones, allowing for better flowrate through them as a bonus!. Brass barbs are made to withstand huge pressures inherent in HP~air lines, a little bit 'overkill' for H2o
