I think you got a bad hose . if thats a washing machine line/ has a rubber inside you cant use it. You need one of those corrogated ones ofr gas. they are yellow alot of the time.

check your pm

ok, LOL i got like 3 of those yellow lines in my room, but the problem with those is brazing to stainless steel, i gotta get myself some high silver content braze

i had a feeling that suction line was gonna be bad, ow well

[blinky]

im going to pressure test the flex line tomorrow, i got this hose if that one wont work i got this

brazing stainless steel to copper can be done with 15% silver brown tip).
with the correct heating and use of white flux

I hear that those hoses expand in length quite considerably, you may want to get one with a stainless steel braid. If you do use it, then I would advise not to run the cap tube inside it but instead wrap it around the outside.

[DGeNeRaT3]

If you can accomplish this build for around $100 bucks, that will truely be impressive. I sure would like to know where you guys get those perfect little condensers.

[Tyrou]

Chilly1 sells these condensers

[_Eduard_]

OMFG where the f*ck do you get all that stuff so cheap? only $4 for a canister of r290 (propane)? and $28 for a 1/5 hp compressor? lol... that would be easily 4x as expensive here... can you build me one too? I'll give ya 200 euro's (about $250)

[REDKEN]

If it's not too much trouble and you have the time.
Could you post the dimensions of the condensor? I'm planning on doing a shroud for one before I get it.


Good luck with your build

Thanks

P.S.:

evap base plate (already ordered)

Where?

[JSU]

you dont need to braze the hose in. just get some 3/8in flare washers and you should make a good/leak free flare connection to the copper.

i spent two hours yesterday at two different stores finding fitings that fit these threads, and nothing fit. apparently these use "compression" threds which are different from normal pipe threads

so.... i gave up and cut off the nuts at the end with my hacksaw, so ill definitely solder this one

They are fine thread 3/8" flare.. I have had luck finding them at lowes and at a local plumbing shop... Only way I have ever gotten a leak proof seal is either to make copper gaskets for them by flaring a 3/8" copper pipe and cutting the flare off or by using this blue stuff called leak lock.. Stainless to brass no matter how tight still leaks, well for me anyways.. Good luck with the build..

[GunnerMan]

Wow 100 bucks, I need to look at Ebay more closley....

Don't use blue leak lock, it's awful to remove and leaks after a few months. It's often the reason behind the failure of many many commercial units (walk ins etc). Loctite makes a good thread sealant, ill try and find the part # and get back here.

I've used the blue leak lock on my cascade. On the 1st stage TEV. It held over 400psi for server hours no problems. And held 100psi for 5 days w/o moving.

Not try to over rule gkiing, but it has worked out for me fine. not only on flaire fittings but on other stuff too.

Yah Ive been using the stuff for two years on various single stage DD units, not a leak yet, not to say it cant or will not happen though.. Im no expert, just learn as I go.

[JSU]

well i hope that doesnt happen to me, i love the stuff! btw blinky you should have asked someone to send you the parts before you cut off the ends. iam sure there are a ton of member including myself who could have sent them in a small envelope...
