A/C Lines

My Vintage Air Lines leaked right after they were crimped & installed by a shop. It finally all bled out & opened the 2 fittings & pulled the O-rings. Two different sizes. Are these standard orings or made special for AC lines. I was going to go up to Kragens, but decided to ask the knowledgeable & reliable members here instead.

Re: A/C Lines

A/C O-rings are not the same as reguler O-rings. You must get the ones for A/C lines. Also make sure you get the right size and lubercate them before installing. Never put them on dry. Also how do you know it was the O -rings leaking. Did the hoses come from Vintage wih the ends attached to the hose or did you cut and have them crimped? The only reason I ask is that Vintage uses a crimping system that at least in my area not a lot of shops had the right machine to properly crimp the ends.

There are no problems only solutions

The hoses came from Vintage but I had to get them cut & then crimped. I didn't know it took a different machine. The shop finished installing the engine at the time called a few shops until they found one to do it. After I received it back a buddy of mine who is a mechanic charged it up, but it leaked badly. He tightened up the fittings & after that it was a very slow drip. The ac worked fine for months until one hot day only hot air came out.
I am trying to get the lines fixed leak free now since we are in the summer time now.
