Designed for Pro Modders, OEM System Builders, High End Servers and Workstations, or any build that requires mission critical reliability. Monsoon's new Hardline Premium Fittings for acrylic tube feature Hard/Lock for a connection you can count on.

The 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. Best of all eliminating the knurling gives your fingers a much needed breakùWorld Class Tools. World Class Results.

Precision machined entirely from marine grade brass with antimicrobial silver barbs/bases so you can run pure distilled or deionized water without the need to add antimicrobial additives that can lower cooling performance. The barb/base also features an internal hex for easy and secure installation and removal,

Available in and color matched to Monsoon's full line of of finishesùincluding all of our compression fittings, standard rotaries, light port rotaries, stop plugs, LED plugs, temp sensor plugs, Silver Bullet antimicrobial plugs, and reservoirs---so you can match, contrast, or accent with total confidence. The O-Rings are premium silicone for years of dependable worry free service and are slightly oversized for easy leak free installation in a wide range of products with industry standard G 1/4 threads. Monsoon's Hardline Premium fittings are also modular and fully interchangeableùbetween fitting styles and across tube types.

  • The Free Center Wrench works on the barb/base 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 diameterùabout the size of a US Quarter, and the machined windows on the compression ring can also be used to provide grip for finger tightening.

The Hard/Lock capabilities of this fitting do not work the same way traditional push in type fittings do and require an additional step. Although they are not difficult to install, we highly recommend you watch the video linked below BEFORE you make this purchase.
