Compression fittings, or barbs/clamps??

both are fine it is a matter of preference on that

Well its all up to you, but I feel that the standard barbs and Clamps have less parts to fail compared to compression fittings especially if you use 45 degree rotary fittings. 1/2 barbs and 7/16in ID tubing with clamps almost never leak. I haven't used Compression fittings but they do look nicer and probably on there own work just as good as the standard barbs but with some blocks you need to use 45 rotary fittings to use then and there in lies the fact there are more points of failure. I would say if you want to spend more money for the nicer fittings go for it. Just make sure you leak test everything.

"1/2 barbs and 7/16in ID tubing with clamps almost never leak"

Yea thats what I've read alot here... and it makes sense, but the only issue I see is that what IF the tubing decided to split because of the added force? Just a thought, and I hadn't really considered it until now.

I love the way the compression fittings look.. also I was mainly talking about the straight ones, not the elbows.

I've always had nice results with barbs and zip ties.

It's always tempting to go for the higher-tech higher-price option, but honestly, 1/2" barbs and 7/16" tubing with anything (I use worm drive hose clamps from the hardware store) have never leaked for me and I will continue to use them until they do leak.

I bought a couple of compression fittings, but the threads on it were really short. So I went to barbs instead.

What 1/2" barbs does everyone here recommend then??

I'm using these type of clamps and these barbs.
The one I got from frozencpu were nice.

i like barbs w/o clamps
i seal it up with a little glue on the fittings

Is it possible to do 7/16 tubing on 1/2 barbs with compression fittings? lol

Possibly, but they would need to have been designed for that size.

I prefer clampless 7/16, or 1/2 with worm drives

I go clamp-less with 7/16" over 1/2" barbs. The tubing is very snug on the barb and takes a lot of force to pull it off.

No because the outer diameter is different on the 7/16, so it wont work..but i do recommend 1/2" comp barbs, i love mine and they are very secure, never leaked on me.
