INFO : Compressions, Barbs, Rotaries.

post #1 of 15
Thread Starter 
This thread has some info on compression fittings, barbs and rotaries. The rotary section might need some revising later. wink.gif

Some info.
The most common material that fittings are made of is copper or brass. Fittings come in sizes for all tubing sizes.
Quote:
ID = Inner Diameter
OD = Outer Diameter
Max Width - Where the fitting is the widest regardless of the location. For straight barbs, this is always the hexagonal grip area.
Max Height - Where the fitting is the tallest from bottom to top. This figure includes the threads.
Max Height When Installed - A measurement from where the threads end to the top of the fitting. This figure can be useful if your application requires a low profile fitting. The o-ring is removed for this measurement.
Thread Type - Watercooling products today generally use BSPP, or G, threads. Other variants include NPT, NPSC, NPTR, NPSM, NPSL, NPTF, and BSPT.
Max ID Thread Side - This indicates the maximum inner diameter on the threaded side of the fitting. (the side you would install into a waterblock, etc.)
Maximum Barb ID
- The maximum inner diameter of the barb. This is where your tubing is placed onto the fitting. The measurement was taken immediately inside of the end of the barb.
Maximum Barb OD - To measure this figure, we used the long edge of a caliper and took the highest data point from the front of the barb to where the tubing would seat.
Minimum Barb OD - We felt this figure was useful to help determine the size of a fitting's lip, or the barbed part of the fitting. The measurement was taken immediately following the barb lip.
Max Lip Height - The maximum height of the most effective barb. Some fittings contain more than one barb, but the first is always the most important, as it is the tallest, and last "wall" of defense against potential leaks.
# of Barb Lips - The number of raised areas on the barb side of a fitting. The number indicated has to be an "effective" lip and not just something that we can feel with our fingernail. What we consider effective is if the height is at least 50% of the initial lip. In the case of the EK barbs, the 2nd and 3rd lips are right around 50% of the first lip's max height.
Weight - Accurate to within 5 grams. If a weight fluctuated within two numbers, we split the difference.

Compression Fittings :
The compression fitting is made up of a nut that screws onto a barb. When the compression fitting is tightened and the correct tubing size and compression fitting is used it will pinch the tubing between the barb and the nut. The following photos are from : http://www.xtremesystems.org/forums/showthread.php?203728-How-exactly-do-compression-fittings-work (I have modified some of these.)

The nut and barb.

Here is an installed tubing on a compression fitting.

Here is a cutaway of tubing installed on a compression fitting.

The compression fitting is a very good choice. The tubing will fit nice and tight. The downside is that they are very expensive.
NOTE : If you chose compression fittings, make sure that the size of the compression fitting matches the size of your tubing.

Now onto barbs... smile.gif

Barbs :
The barb is a compression fitting without the nut part. With barbs you can put a slightly smaller inside diameter tubing over a barb that is slightly larger. This creates a tight fit, thus a better seal. (When doing this, you do not absolutly need clamps.) Barbs are very simple. They are simply a fitting with one or more "barbs" that push outward on a tube in attempt to keep it's position constant. The most common barb sizes range from 1/4"ID to 1/2"ID. Barbs come in different colours that range from Brass, Shining Silver, Black Sparkle, to Matte Black.

Brass barb

Black Sparkle barb

Matte Black barb

They make little, short barbs for tight spaces like these:

Rotaries :
Rotary fittings are designed for tight bends and hard-piping.

All I know is Barb is ugly, especially with the Hose Clamp installed on the Barb.

I prefer compression fittings, but man - they eat your thumbs.

You're able to use kinds of fittings/adapters to replace tubes. Then there's no compression fittings needed.

That's an extremely exotic animal you're referring to. I've only seen a handful of builds that go completely tube-less as it seriously comes at a high premium and a cost of flexibility. (They're still a type of compression as you're compressing an O ring instead of a tube )

Yeah, and I've seen many enthusiastic Chinese guys who did this.
A large number of Bitspower fittings/adapters/rotaries/extenders......which form a metal tube!

I use barbs with plastic clamps. Maybe someday I will upgrade to compression fittings, but for now, the barbs work fine and were much cheaper.
