Garage sell time

[KreKol]

It is garage sell time again. I went to a couple yesterday and the first one I went to had a unopened refrigeration dual manifold with hoses. I paid $10 for it. He saw that I was interested in refrigeration and I explained I needed the manifold for work on Soda Machines. He took me into his garage and offered me a Vacuum pump that he had made himself. He turned it on and after two strokes of the pump almost did not get his finger off of it. I paid $25 for it. It weights over 50 lbs. He started digging trough his tool box and pulled out some grill combs, some odd connectors, and a connector that could solve trying to recharge a machine that does not have any connections. This connector could be attached to that pinched off line that was originally used to charged a system. I am going to send a picture to a friend who is a heating and air technician and see if he can get me some more of them. This one seems a little big for the current lines in the machines I have so I hope they make a smaller version of it. Tomorrow I am going to see if it will fit on the line of one of my machines that already has a hole in it and see if I can get a vacuum. Later on I will take a picture of a Dr Pepper Clock I picked up at a flea market the same day.

Krekol,
I am not that knowledgable when it comes to refrigeration, but that looks very similar to the water line taps sold at Home Depot - I am sure they would not work though -  just an observation. I wonder though if some kind of collar could be used inside - maybe brazed on. Eric at Global Compressors may be the one to ask!

The connector show in the picture is made by WATSCO who is a HVAC Manufacture.  The hoses for my refrigeration manifold screw right on.  I could be wrong but to me it is worth looking into.  It would save me time and money.

Hi,
That is a refrigeration line tap, there are various sizes that you can get and normally one tap comes with at least two differant size sleeves so it can fit three differant sizes of copper lines.

With the tap you can evacuate and recharge refrigeration systems.

These are generally used when there aren't any service taps on the unit.

Thank you for the Information.  I now have to get my friend to order me some.

Be careful, These have a been known to leak. '>

It would be nice if this tapping T was copper.  Then would you be able to punch the hole and then solder both sides to prevent leaking fro that area at least.  Then you would only have to deal with the valve itself right?  Just a thought.

The copper line valve is widely available and the preferred method of tapping and re-charging the system.  It also looks more like a factory installed item.

I use a tool that pinches the line shut, then solder in a copper fitting with a scharder valve in the end of it. Then you use the same tool to round the crimped area back out. Works well. I also use line taps by Wagner, similar to the one in the photo because the stuff I work on usually gets replaced before it ever gets a chance to leak. The best method is to solder one in place.
