    Well, that's the question. Are compression fittings worth the extra cost? Do they reduce the risk of leaks?

    For the price, good tubing, good barbs and the right snap clamps work well - granted all the sizes are correct. The con is that you usually have to slit the tubing to remove them, that is if you've got the right fit.

    Compression fittings are convenient and work better, but think are less forgiving of OD. Usually you don't have to slit tubing to remove.

    Intereseted to hear other opinions!

    well I run plumbing for a living, and in my experience it has been unless you run copper or hard plastic(PEX) they usually leak. But I am dealing with a lot more pressure.

    My guess is they wouldnt still sell if they didnt work, but if they did leak a bit you'd have to go at tightening with pliers, and thats gonna mess up th finish on the nut(if you are that anal to care).

    I say start with 2 on the res or something and see how they work out?!?!?!

    This is what I use:

    Haven't had a single problem! *crosses fingers*

    Oh and I use 7/16" ID tubing so I don't need clamps, they stay on tight enough to prevent leaks. Just dip the end into hot water to soften it up and put it onto the fitting. Works VERY well.

    Nice fittings. As far as the tubing goes, I'm running 3/8" since the Maximus Formula block is 3/8".

    Yup, If I don't go compression, I'll pick these up.

    I just PM'd Cyberdruid. He is recommending EK fittings. I've asked him to post his thoughts on compression fittings.

    I've used both EK hi-flow and D-Tek fittings.
    In my opinion, EKs are better because D-Teks have sharper shoulder that hugs the hose very tightly whereas EKs aren't so sharp which makes removal of the hose easier. But ofcourse, not too easy so it doesn't come off by itself. EKs also feature 2 additional metal rings after the shoulder that make sure water can't possibly ooze out from between the hose and the fitting.

    Compression fittings are really suitable only for hard tubes, I'm not sure even if they work with Masterkleer. Certainly they won't work with Tygon R-3603.

    Seems like everyone is reccomending high quality barbed fittings, I agree.

    My system has only those and in 5 years, I've never had a problem.

    I think the critical factor is the fit of the tubing on the barbs. It should be really snug w/o a clamp. Thinner and softer walled tubing is probably better as less stress on the connection, and more likely to "mold" itself to the barb. Unless you have some severe bends needed in the tubing, kinking won't be a problem. With soft, tight fitting tubing, the clamp is more insurance than anything.

    The 1/4 NPT part is another story - I saw a link around here for a mini-guide W1z posted about how to use teflon tape on those.

    Yeah, I saw W1z's teflon guide, then I went tape happy and taped all of my barbs. LOL

    Maybe good barbs are better,but i really like the look of the compression fittings,though maybe not enough to spend £40 on 'em.

    Have a look at this to give you an idea of what they look like,Notice how big the 1/2" ones are.

    http://www.xtremesystems.org/forums/showpost.php?p=3375202&postcount=1

    Incidently,none of my barbs are taped,and i have no leaks.

    Nice looking system.

    The only issue that I know of for the compression fittings is that the OD (outside diameter) is critical, which isn't the case for barbs.

    And the teflon is for the threaded 1/4" part not the barbs!!! :)

    I just went to lowes and picked up the plastic ones in the plumbing section. Been using them for years, no leaks, no issues....I think they cost maybe $0.45 each. Although the steel does look a lot nicer. So if your trying to win the blue ribbon for appearance I can see the need.

    $3.00 plus shipping makes those expensive little barbs.

    I started out with compression fittings from swiftech, they were a PITA. Quickly removed those and added simple and cheap plastic barbs.
