Tired of big ugly wrench flats on your compression fittings or tearing up your finger tips on knurling? Then Monsoon's sexy new Free Center Compression Fittings are just what you’re looking for. The new patent pending Free Center Wrench design used to tighten the barb and the compression ring is perfect for tight spaces because it puts the wrench above the fitting plane giving you more room to maneuver than a conventional wrench. The small wrench notches on the compression ring are also a lot less noticeable than big ugly wrench flats or knurling on the side of a fitting which is normally the most visible portion when installed.

The patent pending windows on the compression ring reduce weight and add some BLING to your rig by allowing the tube to show through and, in a pinch, provide extra grip if you need to use your fingers. The barb base also features a knurled surface to help the barb grip when installed.

Measurements:
Outer Diameter (A): 3/4"
Wall Thickness (B): 1/8"
Inner Diameter (C): 1/2"

• Barb and compression ring machined entirely from brass.
• The Free Center Wrench works on the barb and the compression ring for hassle free installation without tearing up your fingers. Don't be a tool!

• Although we highly recommend using the Free Center Wrench, the barb can also be tightened with any coin 1.6mm thick and approximately 25mm in diameter—about the size of a US Quarter, and the machined windows on the compression ring can also be used to provide grip for finger tightening.
• Smaller visually and physically to make mounting in tight locations like CPU blocks easier. Outside diameter is just 24.4mm (.96 inches) and total height is just 16mm (.63 inches).

• Knurled base on the barb to increase its grab when installed.

• Available in 8 colors and finishes.
• Includes a black O ring AND a color matched UV O ring—your choice. (Chrome, Matte Black, and Black Chrome get a second black O ring.
• Available in singles or in money saving SIX PACKS that also include a free Free Center Wrench!

these look awesome on your wc setup! super easy to install. however the only down side is that it did not fit on the Bitspower d5 pump mod kit. you would need an extension since the plug gets in the way.

I just built a loop with eight of these 1/2 x 3/4" fittings. They work as advertised; very cool, very elegant concept. Be careful though if you have threaded ports that are in a recess, or well. The large threaded diameter for the compression ring may not clear. My loop is running right now, powered by two 655 pumps in parallel. Not a drop can be seen anywhere, on the first try.

The ability to tighten with a tool is genius. Just mke sure to apply to your reservoir before you bolt it down to your case or else itll take a lot longer. Also this thing is great for changing liquids as it can be taken off just as easliy as put on
