Air conditioning hose replacement

[Delorean Industries]

It ended up being close to nine pages long and includes handy pictures, diagrams etc. Should keep you out of trouble.

I bought the full kit with hoses and compressor. My kit included all of the fittings, hoses, accumulator, orifice tube, hose clamps, etc., and a new back plate for the compressor. I contacted Josh and he said the compressor will ship separately. It should be here any day. New condenser is on the way from John Hervey, and should arrive later this week.

I'm not an automotive air conditioning repair guy.... I own a drive-in movie theatre, so I really don't have a clue how all of these fittings are supposed to connect to what.
I know I can call Josh if necessary, as he has been more than helpful in the past.

Trying to decide if I tackle this on my own or take it all to my local mechanic and say "You figure it out".

Does anyone have a completed set of photos they've taken of this installation?

I tried the JH condenser a few years ago. The holes didn't line up w/ the ones on the radiator, so it went back, and I ordered a new one from DMCMW. I'm surprised you didn't order all of the parts from the same vendor?

We are currently out of stock on our condenser assemblies (now made in house like our radiators and waiting on core components).

This brings up a good question. Are the valve cores used in A/C systems made with specific compatible materials and rated for high pressures? IE not your typical tire valve core.

Hi there,

I want to change the 2 Schrader valve cores on my compressor when I open up my A/C system, and I have a few related questions on replacing them with quality, appropriate ones:

1) What valve material is best, aluminum or brass?

2) What seal material is best: HNBC, Neoprene, Teflon, etc?

3) I understand they are a standard 1/4" size, correct?

4) Any preferred brands, like original Schrader, etc.?

I have the original compressor with brass caps, running R12. Given that this is reported to be one of the most common leak points in the system, and you can't change them once the system is full, I figure choosing the right ones would be good.

Thanks,

You can simply Google A/C valve cores and that will bring up the appropriate ones. They are different seal material from tire valves.

You could just go to your local Auto Parts store and see what they have for A/C type valves. Take an old one with you.

When I replaced my A/C lines earlier this summer, I had to remove the cores from the replacement charge ports to install 134a quick coupler adapters. These are those removed cores.



They are a combination Brass and Stainless steel construction.

AC valve cores usually are deeper in the stem than a tire valve so you probably will need the removal tool like this.
