Fitting's question...

[techtonicpc]

Okay, this may be a dumb question, however I have only used regular barb fittings in my builds before and so this will be my first build with compression fittings. Can someone tell me the different applications with these two fittings?

I am doing a build in an Obsidian 800D and am trying to figure out which of each type of fitting I am going to need...

For now it will be CPU watercooler only with one loop. So assuming I put the pump on the bottom, 3X120 Rad up top, and then the res in the middle (it's a LUND), which fittings would I use for optimum flow and great looks/tube routing.

Thanks in advance.

the rotary rotates at the bottom of the fitting..

the only think I could see this being useful for is pre installing the fittings on the tubing then into the build... and don't understand why anyone would do that if they're using the correct sized tube.

depending on the block you are using, you might need a 45degree rotary fitting or two, but otherwise stick with straight compression fittings matching your tube size.

I have no idea rotary straight compressions even exist....or non rotary 90 degree fittings. I guess they're meant to go together though, there's also such a fitting known as a 'Rotary 90 degree compression' which will cost less, be smaller and generally make more sense.

The rotary straight would make sense on a GPU full cover block if you want to put it on PCB side. At least on my EK blocks i cant put 3/4" OD compression fittings on PCB side due to the outer ring hitting the card PCB so i had to use extenders. I guess the rotary part would work as an extender... compare to the price of regular fitting + separate extender of course if it makes any sense.

You dont really need rotarys unless your limited to space, i'd stay away from them and use some 45's and 90's.. remember compressions match the tubing size unlike barbs ..

That doesn't make sense. It's rotary compressions, not rotary extenders. (though they're a little taller) So, if you wanted to lift that rotary compression off the block, you'd still need an extender. Or you could just have a tall fitting without the rotary portion and it'd still work.

Never needed to do that though as I use 1/4" ID, 3/8" OD fittings.

The only case I can think off is in extremely specialised cases like this one:


where there's a moving part which can benefit from rotation of the fitting instead of the tube.

From the photo on the link he posted, it looks very much like a rotary extender to me.. Like an extender, just rotary ? Like i said if it's cheaper than regular fitting + separate extender, why not...

[Fatfool]

Oh btw, TS, you could have hidden your res away like I did (this is a 600T but it's close enough)




Need a Swiftech Res though.

yeah It seems like an extender with a rotary portion. Which would be quite pointless as a simple non rotary extension part would do. Gotta factor the risk of rotaries leaking too so in this case, I'd rather go for a non rotary extender.

Alright, I appreciate the responses. I just could not figure out what anyone would do with that thing
