I wanted to have R3400 tygon for really long time, because of its awesome looks (for those who dont know, its pitch black).

USPlastics have the R3400 in 7/16id (which is what I want), but od is 9/16, so tubing walls are 1/16, about 33% thinner then 3/32 walls on 5/8od. Are 1/16 tubing walls thick enough to prevent kinking, compared to 3/32?

mmm R3400

The R3400 is some very nice tubing. I was using it for my old low flow setup in the 8/11.2mm variety.

I'm now in the process of setting up my 1/2" ID rig and would like to use R3400 again in parts of the loop. I have no idea about the 1/16 wall thickness though?

Nice price at USPlastics. McMasters wants $3.88 per foot for the 1/2" x 3/4" tubing.

Where is Crediki when you really need him? :)

1/16" wall is too thin to make the tubing useful - you want atleast 3/32" wall thickness with any tubing to prevent kinking, especially soft tubing - tygon being so soft, if it has walls that are too thin, it will kink because the tubing caves in on itself because it lacks wall support, rather than kinking because its not flexible enough

Yeah. I have (among other things) masterkleer w. 1/16 walls, and I can only use it near the outlet of the pump, where the high pressure keeps it in shape.

their is 1/2" id, 3/4" od 1/8" thick walls.

Yeah, apparently the only good size for R3400 is 1/2id 3/4od. I wanted 7/16id, but alas, 1/16 walls are too weak.

I'm using this tygoon for my setup. It doesn't kink so easily and u can help the situtaion in the difficult spots with coolsleeves. Of course 7/16"-5/8" is a better choice (i would upgrade to it when i'll redo my loop) but i would prefer it over 1/2".

I think I'll just buy bit of both - 1/2id and 7/16id, both in R3400 formulation.

R3400 is slightly harder then R3603 -> durometer rating 64A vs 55A, so in theory, it should kink less.

Thanks for the help :toast:

majestik...be sure to take some pics of your loop and share your opinion of the 1/16 wall R3400.

The black tubing would be a good way for me to "stealth" parts of my loop on the other side of the case. Not sure how I'm going to handle that part yet. Anyway...looking forward to your opinion on the tubing.

Nice Joe! What fluid are you using inside your loop?

What do you think of the PrimoFlex (http://mountainmods.com/index.php?cPath=35_46) tubing?

Joe, it looks very nice, tubing looks very sleek.

If you push a nail through a tube, how many times does it cut the walls?

I definately will, but first need to find a way to smuggle it into Canada

Do they ship to canada or no? if not I'm willing to play the middleman as I live in Wisconsin, somewhat close to the border, so I could mail it with a low declared value if the store isn't willign to ship to the folks up north ;)

I'm using this (http://www.alphacool.de/xt/product_info.php/products_id/1181/cPath/5_54_57/water-additives/water-additive-fluroprotect-green-uv:.html) UV-Dye. Running for 2 months now and my tubes are still clear.
Don't know about primoflex. I know it's a better solution to have UV tubes rather UV dyes but for now i prefered to go with the latter solution cause i wanted 7/16" tubes and preferably Tygon... :)

Thanks Joe. I got some Masterkleer 7/16 ID in yesterday and I like the way it fits and looks vs. the blue Primoflex. I imagine the Masterkleer 7/16"ID will be easier to route as well.

I wish a US retailer stocked that Alphacool green dye as it would be cool to have some green "bling" in my loop.
