PrimoChill Compression Tube Reservoir Review

Installation
The first thing to do when installing the CRT would be to slip the mounting bracket around the reservoir.

With the bracket around the reservoir slide the bracket base onto the bracket.

Now simply install the nylon thumb screw and tighten until snug. I would not recommend using a screwdriver on the nylon as it will strip easily.

Repeat for the other bracket.

When installing the reservoir into a case you will of course want to pre drill four holes for the bracket base. Then with the base lined up with the holes, thread the metal mounting screws through the case and into place.

For our testing we are only going to fill the reservoir with water to test it for leaking. This meant installing 6 plugs into the 6 G1/4 holes of the endcaps. Take care when threading into the G1/4 holes. Delrin, the material used in the endcaps, is very soft and cuts easily. You can easily cross thread the holes. Also if you are not careful you can easily scratch the caps as well making them look bad aesthetically.

End Cap Removal/Installation
Although not recommended by PrimoChill we wanted to make sure to test all aspects of this reservoir which means taking apart/removing an end cap and reinstalling it.

The first thing to do of course was to remove the four screws holding the pieces together. This is done with a 2mm allen wrench.

As you can see there is an oring on each allen screw to keep them from leaking.

With the outside end cap removed you can see how the oring sits on the outside in between the two and is pressed into the groove to form a seal.

Simply pull the oring out and using your allen wrench as a hook, pull out the inside compression plate.

Now the more tricky part, re-installing the end cap.

The most important thing here is to pay attention to that line around the inside of the reservoir. If the compression plate is above or below this line there is a great chance your reservoir is going to leak.

To put the end cap back together place the oring on a flat surface. Then place the compression plate on top of the oring.

Now slide the reservoir over this onto the flat surface.

With the oring and compression plate inside, place the end cap on the reservoir and thread the two nylon thumb screws through the end cap and into the metal threads of the compression plate. Tightening them pulls the set together.

Once they are close enough you can install the allen screws back in place. Make sure the orings are in place on each screw. With the first two screws in place you can remove the thumb screws and replace them with the allen screws. And that’s it, end cap removed and re-installed. I would suggest capping the holes and filling the reservoir before installing to check if you will have any leaks.
