Compression Fittings

post #1 of 8
Thread Starter 
So I just received all of my WC'ing parts and I'm excited to get started with water to say the least, but I have a question about the fittings I chose. The compression style fittings don't have a wrench head on them like barbs do so how do you tighten them to the devices? I've read that you get any fitting finger tight and then a quarter turn to snug them. Well.. these threads are sharp! I shredded my fingers just playing around with them on a scrap piece of tubing.

Also, I chose the XSPC Dual DDC Dual Bay Reservoir. Right now I've got all the pieces for my CPU loop but I'm going to be adding a second pump and rad to the res for a GPU loop. Is there any problem with leaving one side of the res empty for now? The water from each chamber can't enter the other, correct? I just want to make sure before I fire up one side only to have the water dump inside my case from the other side of the res lol.

A question about running 2 pumps in series as I've read that it's more beneficial in a restrictive loop (I'll be using all XSPC blocks.) How would I do that with my dual bay res with 2 MCP350's? I imagine the only way to do that would be to run one tube from the outlet of chamber A on the res directly to the inlet on chamber B but I don't know if that would add more flow or not? If not then I'll just make the loops separate.

In case it's important here are the parts I chose so far:

XSPC Dual Bay DDC Res - Link

XSPC Rasa CPU block - Link

XSPC RS240 Rad - Link

MCP350 DDC - Link

PrimoFlex 3/8ID x 5/8OD Tubing - Link

XSPC G1/4 - 3/8ID x 5/8OD Compression Fittings - Link

Indigo Extreme! - Link

Silver KillCoil - Link

I really appreciate the help guys/gals. Also, if you're curious, I chose the RS240 only because of space restrictions. I have a 600t and that's the only thing that will fit internally. I'm going to have to add a RX240 on the back of the case with a rad box or similar for the GPU loop later.

Not sure on the pump issue. But for compressions, just tighten them as tight as you can with your fingers. Yes, your fingers will start to hurt; if it bothers you just throw some gloves on.

you just hand tighten the compression fittings. I've done so for almost 2 years on multiple builds and never a leak from them

Thanks for the replies about the fittings guys. It's just beginner's nerves with watercooling. Does anyone have any tips on the res and keeping one side of it empty until I get my other pump and loop set up?

There's a small wall between the two sides. You don't have to worry about it. I have that same res sitting around here somewhere, just never use it.

Work with your hands more. :/

You could also get a pair of robo grips and put some rubber over the teeth, those will get those things tight....

I'm a lead tech for a communications company. I crawl through attics, climb poles and crawl under houses for a living. All the joints on my hands have a callus.. When you remove the 'collar' from the compression fitting and try to screw the G1/4" side of it onto a block the threads are very sharp and left pieces of shredded skin on the fitting. Believe me, it's the quality of the fitting, not the weakness of my hands.

Thanks for the info on the res, I can stop worrying about it. +rep
