is this ok to use as a flex line?
first is the pipe from the wc ''blader'' lol
second from the cooking machine!
:woot: :woot: :woot:
ps: if any1 can pm with the lengts and components necesarry for a nl11f r404, flex about 60cm, condessor21cm per 25!?!? will go on a fx55
thx

:rofl: Straight to the point there chilly1. Can just imagine going to the toilet at quintus's place and flushing the toilet and having water go everywhere cause he's flogged the fill line :D

:slapass: shut up man cause to get the condes i have to destroy the air conditioner shiat my father will go nuts :banana: :woot:
rofl the things people do to cool there pc! :D thats why i love you guys because you are all so Xtream :banana:

seriously man, I don't want to offend you or anything, but if you know this little about phase change, I do not reccomend you attempt to build a unit. If you do and it goes wrong, which it most definitely will if it is a first attempt, you could SERIOUSLY INJURE, MAIM, or even KILL yourself. We don't want that to happen, so get professional help with your first build, or just don't build it.

The flex line doesn't have to hold pressure, but if it is weak it will collapse from higher external pressure. I have seen suction line pressures of 0-3 PSI, but whats the PSI of air at sea level?
(I'm thinking that if you had good skill you might be able to make do with a weak flex line if you had internal and external pressures matched. Not stupid enough to try it though).
Edit: Standard atmosphere at mean sea level is somewhere between 14 and 15 PSI. I'm guessing that at that pressure some liquid would not vapourise and liquid slogging would become much more common.

Hmmm..Do you understand that when the compressor is off both sides ( high and low) will be at the same pressure? I doubt that water line can hold 100psi lol!

I HOPE it is not 100PSI eqaulized no matter what ambient temperature is.

Why? My systems are usually 80-100 psi off

:cool: Hey Hey flex line NEED to hold pressure,operating it can work at pressures close to 0psi or even vacuum,but when you turn off the flex line should whrist the static pressure of the system,just use a copper or stainless steel flexible line

When people say 0 psi, that is equal to atmoshperic pressure as it's measured relative to the pressure in the atmoshpere. It's known as 0 Gauge pressure, if you have 0 absolute pressure, that means you have -14.7psi, or a perfect vacuum, something that is very hard to achieve on earth, exists in space but. So 3psi is actually 17.7psi absolute, it's just that the atmosphere outside what is being measured is actually sitting at 14.7psi anyway, so it's really got a relative (or gauge) pressure of 3 psi, understand???. Sorry, i'm not real good at explaining things.:slap:

no such thing as negative pressure. Even if the pressure outside the line is greater then inside does not make the preassure inside negative.

Negative pressure is just vaccum, when refering to gauge pressure that is. If you're talking absolute pressures (which is used mostly when refering to vacuum conditions), there's no negative pressure.

Did you know that 0 psi is 30 inches of vacuum. That 0 PSIG is actually 14.7 psi commonly used as the referance point for all Our measurmants when dealing with pressure.
BarG and PSIG THe key here is the G The key is the G This means guage.. and that you refrence is the guage.. 0 or 1 atmosphere.

That's a bit clearer then the way i said it. I was always a hopeless tutor, my students never understood what i was talking about :(
umm not trying to hijack your thread dude but i thought i might as well ask here.

Would this be any good as a suction line. Its solid copper tube and its nice and bendy XD and its 1/2" ID

Maybe a missed point is the rubber that used in that hose. Its not meant for refrigerants, and they will permeate the rubber and leak out. Barrier hose is the correct type of rubber hose to use in phase change.

don't think so, move it few times and you will have a leak:)
not really planning on moving it around that much lol. anyidea where i can get a good suction hose in the UK with out having to sell my car for cash lol

Thats corrugated copper tube , usually used as flexiable fill tubes for water heaters. I,m not sure of the pressure rating so I can't say for sure.Do some research to find that out. As far as permabilty its fine ,its solid copper!!!
my guess would be it would work ok, but find a pressure rating. Burst pressure shoud always be 3 to 4 times working pressure.
k will have it checked out. i guess i should probably just go out and get the proper thing from chilly1

chilly uses corrugatted stainless steel, which would have a higher pressure rating,but if your corrugated copper is in a acceptable pressure range it would have the benifit of being easy to braze and of course you already have it.
Corrugating reduces the pressure rating of a tube thats why you need to check.
I have a feeling chilly already considered these and chose stainless for some reason, higher pressure rating I,m guesing!!!!!! but it depends on the gas you are using. how about we ask .
Whats your thoughts Chilly ??????

no problemo boyz an girls i go for the right stuff. dont whant no boom or leaking or strange reaction rubber with r**

Actually I liked how you put it. I think we thing the same way :)

I was also wondering about this. Wanted to use this as well. I wonder if chilly1 can make a post and educate us on how sutable is this for suction line use.
