Introduction: DYI INLINE FILTER, PC Water Cooling
For Computer water cooling there's not a lot of options for
inline filters that offer capacity and high flow.
This Kurig "MY K Cup" seemed to me like a perfect solution and was basically only lacking a set of G1/4 fittings. and since my Kurig 1.0 died and the new 2.0 dosn't work with these, don't get me started , it was just taking up room anyhow.
I started By running the K cup under the tap to gauge the flow through the mesh basket, which is surgical stainless by the way. and happily it drained as fast as the tap could pour and the water never crested the top.
Dielectric Grease or Vaseline
Step 1: Dremel the Nub Off the Bottom
The Cross of plastic in the bottom is more problematic then you'd think. be careful here.
Use the dremel to remove it or come in from the side with the cut off wheel and cut that nub off to make room for the Tank fitting
Step 2: Clean Up the Hole
Now use the Sander bit or a flat file to clean up the hole. The bottom is curved but we want the Tank fitting to sit as flat as possible so the O ring makes contact on the outer surface.
Install the outer part of the fitting into the MY CUP,
I choose to apply a thin layer of dielectric grease to the O ring
Step 3: Install the Bottom Tank Fitting
The Tank fitting comes with a 7/8 nut and stainless washer, the washer fits perfectly at the bottom of the K cup and creates a flat surface for the nut
Add a bead of Water pump RTV sealant to the bottom of the washer to aid in sealing.
holding the Cup upside down balance the washer on the tips of your fingers and move it up into the cup to fit around the shaft of the tank fitting. Clean and wipe the inside of the Cup
NOTE: Water pump Sealant has a high resistance to Antifreeze and other chemicals,
It is a sealant not a glue, if you want a glue, use 2 part epoxy such as JB marine weld
Step 4: Add the Nut
Add a small bead of sealant to the bottom of the nut and place inside a 7/8 socket on an extension.
Hold the cup on its side and movie the nut in over the shaft of the fitting and spin on by hand. now hold the flange of the tank fitting with a vise or a crescent wrench and final tighten the nut using the socket wrench but use good judgment here
Step 5: Add the Top Fitting to the Lid
If you use another tank fitting for the top you will need a second washer to use on the outside of the lid because there is a recess that could effect the O ring, repeat the steps used on the Cup for the drilling and use of sealant
use a dremel wheel to cut off the little fins under the lid
I decided to give my new tap a try, If you use a G1/4 tap make sure you drill it first because the hole that's there is way to small. I managed to get some good clean threads cut into the plastic but I decided to use a touch of water pump sealant on the threads of my barb fitting before a set it to the lid
Step 6: Leaktest
wipe down all the parts and apply a thin layer of dielectric grease to the basket along the top and bottom of the rim replace the basket and lid, fill with water and check for leaks then install in the water loop so the flow goes threw the filter before your pump. I have this one running in a loop using a D5 pump with a VGA and CPU cooler with out any issues. enjoy
We have a be nice policy.
