Can someone explain O Rings please?

post #1 of 7
Thread Starter 
i've done a lot of reading about water cooling, and sometimes come across someone talking about O rings, but i can't seem to find a simple explanation about them.

i gather they're used to help prevent leaking?

can someone help me out with an explanation of them, and whether or not i need any with the following fittings? i'd really appreciate it.


Compression Fittings
Enzotech 3/8" ID 5/8" OD Silver x 6 (~$36)
http://www.jab-tech.com/Enzotechnolo...r-pr-4680.html

Barbs
Danger Den Fat Boy 3/8" x 6 ($15)
http://www.jab-tech.com/Dangerden-FB...b-pr-4213.html

Rotary
Enzotech Matte Black 45 Degree Rotary Fitting ($7)
http://www.sidewindercomputers.com/enmabl45dero.html


from what i was reading it seemed that compression fittings don't need them and the Fat Boys come with them already? is that right? and what about the rotary?

thanks in advance!

O-ring is to prevent water leaking, mostly is where the water being pressurized through the gap O-ring fit in that gap to keep the pressure contained.

Rotary, barbs, and compression fittings all have O-ring just given at that angle from the pictures doesn't present the O-ring.

Rotary the O-ring is placed in the joint (twisted area) so is hidden to the eyes.

If you look at this picture the O-ring is green color,

O Rings are small rubber rings used to form seals. I'm still new to watercooling myself but I would think you use them on all fittings, it would be placed on the end of the barb where it screws into your block/rad/res. You can see them in the Danger Den Fat Boy picture.
