Question how do you get the evaps so polished and shinny again after you braze them?
They look like they have never been brazed

[gosmeyer]

Zero atmosphere oven is the easiest! No Oxygen, or you could spend time polishing !

Just after brazing - grinding using various sandpapers (dry), then 10 hours or more bath in "lemon acid" (quite strong mixture with water), then cleaning using steelwire brush mounted on driller , then wet grinding using sandpapers, then polishing .

@chispy: Yes, that 100 cm with black sleeve is Yours .

Hi i need some advice about Suction Lines, i will use Stainless Braided with Rubber Syntehtic PVC Hose, i will use it for my SS with r507, i have 2 Question, first if i braze the fittings the inside rubber hose wil burn o r break? and second ther r-507 an their Oil wil do some erosion in the rubber walls of my hose?

Thanks For yor Advice

[piotres]

Forget about brazing any hoses which are built using any rubber part .

I recommend to use 100% stainless steel hoses (brazed, not screwed to evaporator) .

2 almost same suction lines - difference is only captube lenght . I must say that 100cm lenght and black sleeve seems to be "standart" suction line .

Thx guys .

I know I'm stupid but I don't understand Your questions (bolded) can You write them in another way??

[Patrickclouds]

which way goes the refrigerant in your evap?
did you braze the cap tube to the bottem that the refrigerant goes from the bottem of the evap through the spiral or steps up to the outlet.
or did you braze the cap tube to the top so that the refrigerant goes down through the spiral to the bottem and then it passes a small hole to the inner of the evap to go up into the suction line.

no problem, my english is bad aswell sow I now what you mean.

these Suction Lines, are they easy to install?
Like when you have a Single Stage unit and you want a new Suction Line. Can you just by one of you and replace it. Without having to do alot of work

As i recall - the Right Picture is the Better way , the cap tube goes all the way down to the buttom,
And than it goes up through the Spiral .

Thx Patrick, but I'm not SUCH stupid that I need such clear explanations .

Captube comes to bottom of evap, so it's bottom inlet.

Not so easy . You need brazing torch, vaccum pump, manifold, and some freon (r507 ) to change suction line .

size of cappilair?

In those two were 300 cm and 350cm of 0.9mm but can be such long as You want .

THANKS!

Shouldnt this be in the for sale section???

[piotres]

Shouldnt this be in the for sale section???

Why ? In that topic I just show some shine and various colors of suction sleeves .

[sdumper]

Nope it was no dig at you I just got very annoyed that I had a thread moved to the wanted section...and this thread is obviously a forsale type thread demonstrated the suctions lines you are selling.

I just want some consistency in the moving of threads
