forming tygon tubing
 

just thought i would drop this little tip (im sure some of u already know)...i had some 1/2 x 3/4 tygon tubing and i need a tight 90 deg bend to go from my gpu water block to my pump(u can see in the pic how short of a distance i had to work with)....anyway i took a 1/2 od spring and slid it down the inside of the tubing and then took a clothes hang and put it inside the spring and bent it to about 15 to 20 deg past 90 and put it in boiling water for 15 min and to my suprise it came out at a prefect 90 degree..


i hope this helps someone

the pic doesnt show my new setup but u can see the tight bend i needed(pics coming soon when i get my new setup done)

lol... tygon DOES have memory.... and now tygon doesnt even bend decent... how is it any different than vinyl? i can do the same boiling water thing with vinyl.

well it would bend like that but not stay at 90 and i didnt want to put all that pressure pushing up on my vid card...i got a easy 1 1/2 bend rad

oh yes it does have memory trust me...but its still better than vinyl

I've filled tubing and hose with sand before and heated it to make complex bends... works good.

ahhh ok i get what your saying.

Look at tubes going to and from my radiator in the front of my cube case (pic in .sig below), quite a bend there. I inserted springs into the 3/8" vinyl tubing and it works great, springs are usually made out of very corrosive-resistant steel and they look as new (in service for a year now). I use 2% water wetter in my water.

good idea, but its killing your flow.

i would recommend putting copper elbows in there.. take some 3/8" silicone and it fit nicely over 3/8" copper elbows. same applies for both being 1/2"

but hey, if your happy with it, thats what matters

hey UpAllNight, youve got some 3603 tygon right? how is that sutff as far as flexability, etc? is it like silicone, or worse? just wondering....

DigitalChaos, yes I'm satisfied and it doesn't kill my flow that much and only lowers my cooling ability by 0.5 C which is within the margin of error.. especially as I only have an in-socket probe.

what i do if my tubing is bending and flattening at a corner i take a zip tie and i put it around the tube so it makes it round agian works goodor if you have any extra hose you can cut a slit it in and put it around the hose in you system to straighten it out

A copper pipe 90 that has a sweeping curve is borderline; 2 copper 45s are better. Never use the 90 degree barbed fittings. Why not just get a small piece of silicone for that one bend?

i would say that its right in between the 2..not as rubber feeling as silicone i can get a 1 1/2 bend radius out of it but it would apply some pressure on the block u are attatching it to...i just like the looks of it better and i dont have a problem working with it at all
