Features    [ Edit | History ]

Our Single Barb Fittings Features and Clamp Dynamics
The threads are molded in precision-ground cavities resulting in perfectly matched threads at the parting line. This produces the cleanest, most accurate molded thread possible.

Why our fittings are better.
Our single-barbed fittings are designed so the mold parting  line stops at the base of the barb. The ridge and the barb's conical  surface are free of the molded-in leak path present in multiple barb  fittings. The conical surface is glass-like and smooth allowing excellent sealing. 

The straight barb shaft provides space for the hose to relax behind the barb causing the clamp to work like a drawstring. This forces the hose diameter to become smaller than the flare of the fitting's barb. If the tubing swells from internal pressure (near burst), the clamp will be pulled up tight to the back of the barb and a tight seal will be maintained.

Why multiple barb fittings fail
Mismatches often occur with poor quality or worn tooling, causing misaligned threads and barbs that result in leakage. With multiple barb fitting designs, it is virtually impossible to avoid creating parting lines on the barb surface. These parting lines create leak paths which become more pronounced as the mold tooling wears.

Multiple barbs are typically in close succession. This prevents the tubing from relaxing to its original size, which   is essential to the barb's performance. If the tubing does not relax behind the barb, the barb is rendered useless, as shown above. (Note the bridging effect.)

Pros
they are easy to use, seal very well, good for adapting 2 size hoses
Cons
they not pretty but its easy to hide them.
Summary
i bought these because i had to adapt my 1/2" loop to my 3/8" barbs on the zalman zw-gb5 water block they are awsome they seal very well, and they are easy to hide behind drive bays.

Pros
Do the job well.
Cons
polypropylene look awfull IMO.
Summary
Do the job well, reduce the 1/2 to 3/8. No restriction since you already change tubing size so your restriction will be your actual setup since your not supposed to change tubing size in the middle of a loop...

Pros
Works, looks ok and it is UV reactive
Cons
Nothing
Summary
These work great and it looks like they will hold out for a long time. Although in my loop it created a pocket of air before the 1/2 end. It went away after some bleeding so it's all good.

Pros
* Looks decent
* Hasn't leaked so far
* Most important: Works.
Cons
None so far.
Summary
Used it to connect my 1/2" loop to my single 120 rad which came with 3/8" barbs only. Works flawlessly, fits tightly and hasn't leaked so far. Would buy again.

Pros
Decent quality,
Cons
platic Fitting
Summary
Had to combine some 1/3 and 3/8 inch tubing, this stuff does the trick. Looks OK enough, and design ensures a tight fit and no leaks.
