mod/smart tip: Baffled on what size you need? Well, you can always bust out the measuring tape and measure the tubing your are attempting to fit. Measure the INNER diameter of the tubing and the corresponding fitting will have a matching or close OUTER diameter measurement. For example, a 1/2" OD Fitting will fit 1/2" ID Tubing.

Once you know the size you will need to determine the type of fitting you desire. Below are the different types and materials.  

Types:

• Barb to Barb
  The double ended barbed fitting is used for manipulating the tubing throughout the case and around the components. These fittings come in a variety of shapes to accommodate any configuration.
   
• Threaded to Barb
  With a barb on one end and the specified thread on the other, these fittings allow tubing to be connected to another component such as a reservoir. Make sure you choose the correct thread and size as well as the correct size barb for your tubing.
   
• Flanged Threaded to Barb (Exclusively designed by PrimoChill)
  Specially designed fitting which allows an o-ring to be used creating a leak proof seal against the wall of the reservoir.

Materials:
