Monsoon EV2 Hardline Economy Compression Fittings, 1/2” x 5/8”


EV2 Boxes

When looking for compression fittings, I really liked the aesthetic look for some of the Phobya and Alphacool fittings - especially the ones with a non-smooth surface like these.

I watch a lot of reviews. The Monsoon EV2 fittings, though not as aesthetically pleasing, were getting really good feedback. People really liked how strong the seal was, and I was definitely looking for that. Originally, I was going to purchase them with Performance PCs engraving service, but I completely forgot about that when it came to ordering time.


Before opening your box, I recommend watching this video by Gene Phipps.


I purchased a few of the 12-pack boxes. Inside you will see 3 layers: A 6-pack, another 6-pack, then the instructions, tool and seals.

Pulling the layers apart, you can see there are a couple bags of seals. You will use either the red or white bag (as instructed) and the black or color-coded seals (your choice).

EV2 Parts

This is what an individual fitting looks like.

When taken apart, I noticed quite a bit of velvet fuzz where the outside seal should go on the chrome piece. I did my best to clean it off. I also noticed some discoloration on the inside, but was unable to address that.

EV2 Open Fitting

Out of curiosity, I checked the chrome piece against the Alphacool mat sizing guide.

The assembly includes two parts. The part that goes on your tube and the part that goes on your waterblock/etc.

Picking the Parts

To determine which seals to use, we need to grab our tubing. I was a little disappointed when I received this tubing from Performance PCs already opened. I’m trying to convince myself that they were making sure that it wasn’t broken; rather than it being someone in the delivery process.

EV2 Tube

Picking a color was not an easy choice. I was going to do a two-toned system; then I thought about doing a UV-reactive system. For this first pass, I decided to go with the Blood Red from Monsoon.

We then have to use the tube inside the informational card. This is the part I don’t like. Every video I watched showed the tube hitting right in the middle - making it seem more like guess work. I think this part of their product could be improved.

EV2 Card

In my case, I decided it was slightly more on the white side than the red. Again, I think it is very much guess work.

More to make sure that I remember than anything, these are the parts I chose.

Just out of curiosity, I decided to see how the tubing looked on the Alphacool sizing guide written on my mat.

For that to be very useful, I think I’d need to cut off the end of the tube and use a smaller piece.


The outside seal slipped on rather easily. I used the blunt edge of the included tool to make sure it was fully seated.

EV2 Outside Seal

I also used the included tool to help seat the first inside seal. A lot of reviews talked about how difficult it was, but I didn’t have any of those problems.

EV2 First Inside Seal

NOTE: You’ll see that it is not all the way at the bottom. If yours is, it is because you did not watch the video above like I suggested.

Installed the second inside seal.

I prepared two of them.

And installed them into the CPU waterblock.
