Best 90 Degree Fittings

post #1 of 35
Thread Starter 
**Update: Which is better performing (or is there even a difference other than looks?)- Black Sparkle "L" Fitting OR Crystal L-Block **

I'm working on my first liquid cooled system and have just noticed that I will almost certainly need a few 90 degree fittings, both threaded and non threaded (and some coils.. ick).

I realize 90 degree fittings will considerably hamper water flow and would like to ensure that I minimize that loss as much as possible by getting the least restrictive fittings.

If anyone knows of a particularly high flow 90 degree fitting (either threaded on one side or double-barbed, 1/2inch ID) I would be absolutely delighted.

Thanks.

Hondacity did some flow tests with different 90 degree elbows. The Bitspower 90's did NOT decrease flow one bit. He had a few & the bitspower ones were top notch. They are a bit more expensive, but totally worth the money. I've got some 45's from bitspower & they are VERY good quality.

There's really so many options, pick whatever you like: http://www.performance-pcs.com/catal...0fabbe39d89ec9

If I was to ever use a 90 in my loop, which will never happen, I'd use one of these..Bitspower G 1/4 Shining Silver Triple Rotary Angle Fitting - # BP-90R3 .There more like a plumbing sweep with a long radius and should flow quite a bit better then a normal hard 90.

Those are actually the ones I was looking at.

I read somewhere that every 90 elbow you add to the loop is like and extra 1ft of tubing. That was awhile ago though and probably not true. Just thought I would throw it out there.

It depends on the elbow... but can add more like 6ft of tubing with the cheap plastic elbows.

Heh yeah I know, but I've come this far, I might as well drop a few more bucks and get it done right.

Yeah that's what I've heard as well. That said I believe that statistic was based off true 90 degree elbows with no curve (the cheap plastic ones that cost a buck each). I'm sure there are better ones that wouldnt be quite as bad (like the bitspower ones, although I'm not liking the price on them all that much. Guess that's what I get for not doing better planning)
