question about 7/16 ID tubing

[evoted]

Hello, i finally put my LC system together and i am using Tygon R-3603 1/2" ID 5/8" OD, but i am almost getting a kink the tubing lost its "radius" (not sure how to describe it) and it looks flat now, i read the review about tubings and i think my best bet would be the 7/16-5/8 from Tygon too.

I just would like to make sure that the 7/16 will solve the problem or should i just buy some sleeve for the tubing.

Here are some pics

tubing looks pink cause i 1st used Feser "red" dye (big mistake) then i drained the loop and used Petra's UV Blue/Clear.

Anyways what you guys think, will the 7/16 do a better job?

Thanks!

The wall thickness of your tubing is too thin to retain its shape. Either 1/2"id x 3/4"od or 7/16"id x 5/8"od will give you better shape retention.

all right thanks a lot!

do you have any other picture angle? besides wall too thin with 1/2-5/8, maybe too much torque or bending. need some more picts.

yeah, definitely use thicker walled tubing avoid easy kinks. 1/2-3/4 should be more sturdier.

i have this other one...dunno if it helps

im trying not to use the computer too much i will order the 7/16ID-5/8OD tygon but if you guys see anything else that i need to change i would appreciated.

yeah looks that it realy is all flatened a bit...
firstly if all temps are good i would say you could just use your pc normaly ;)
and next to what the other people said like thicker walled tubing you could also use the same tubing but let the tubing longer then it now is what lets you have a less tight bend thus less flatening...

my temps are
E6750 @ 3.36 47/47c @ 100% load, orthos and core temp.
8800GTS 512 stock 970/1670 @ 42C
ambient is 34C

PA120.2 with 2 YL 12SM pull config.
Fuzion V2
MCW60-R2

your tube shouldn't be kinking atm - there are NO tight bends!
So looking at ur setup i'd be suprised if it's kinking/pinching, but that run of tube from the pump looks a bit iffy, get some coils. But mainly it looks like if u had an extra inch or two (or 1/2") on each run of tube you would defo be ok!
Good luck and let us know how u get on

Try switching around the two connections i have marked(if you can),the one going to the right will not flatten so much if its on the right hand gpu block connector.The one going to the pump may need to be longer or have a coil around it.

It looks to me like several of your runs are too short but if it works well then run it and next time make the runs where you have flattened tubing a bit longer.

I just looked again at those pics and I would just replace all of that tubing, it's way too short in a couple of places...that run from pump to res looks REALLY bad.

If you read the "Tubing Review - 18 Types of Tubing Reviewed [56k warning (http://www.xtremesystems.org/forums/showthread.php?t=157370)]", it states that


Summary:

Overall, the best tubing for kink resistance is one which has the thickest walls in proportion to it's diameter with the highest durometer being a second consideration. Thus the Tygon R-3603 7/16" ID with 11/16" OD (1/8" wall thickness) provides the best kink resistance of the tubing suitable for 1/2" barbs. For 3/8" tubing, the Primoflex 3/8" ID - 5/8" OD (1/8" wall) is by far the best choice for kink resistance on tight bends.

Therefore, if you go with the tygon R3603 7/16"ID, 11/16"OD you will achieve the best bend radius.

Another thing you can do is change your layout.
Reduce the amount of tubing by running
Pump>Vid Card>Processor>Radiator>Res>Pump

It does not matter which order your loop is.
However there is a bit to gain from having less tubing in your loop.
