With a fitting like that, you will need a clamp too to make sure their is no leaks.
But you probably don't need all your fittings to be 90 degree swivel.
There you kinda have to visualise how your build is going to go or you can order a few of each fitting and RMA what you don't use .... that's what I do.
But make sure your supplier will agree to RMA the fittings you don't use.
I won't RMA the ones I don't use. I'll put them in my computer accessories box (it has all sorts of stuff from stock coolers, thermal paste to unused drives and even a Blue Orb 2) for future use.
I should use 90 degree fittings for my GPU as my EVGA GPU will be behind an air cooled workstation GPU. The only way to get around the air cooled GPU without putting in 90 degree fittings is to make the tube make wild twists and turns around the GPU resulting in kinking.
I could make my own cooling plate for the Quadro like this person did
but I haven't even made a water cooling system yet and I am hesitant on making my own. If the Quadro had the same reference designs as a GeForce card, I could get a hold of one but sadly I don't think it does.
