I recently had my 71 converted to 134. I have a leak at the low pressure 134 adaptor. When I take off the cap, it is leaking at the schrader valve. When he installed it, it was leaking and he installed a second valve. Still leaks and I cannot fully seat the 134 freon charging adaptor. It almost seems like he tightned the 134 adapter too tight.
What do you recommend? Do I need to get a new line and 134 adaptor or?
Thanks in advance for your advice.

He was probably using a cheap aluminum adapter. Try a different brand, made of steel.

I tried two other adaptors, still will not seat properly.
Any additional advice is welcomed. Any recommendations for the leaking valve?

What do these adapters look like? (Post pics if you can)
Are they aluminum and fit around the original service port, using the original scharder?
Are they brass/steel and require removal of the old schrader?
Some other type?

I would recommend the brass conversion fittings available from NAPA. About $6 each. Never had one leak.

Yes, I used the aluminum ones that come in a kit. I will have the adapter changed to the brass or steel with a new valve incorperated with the adapter. Thanks for the information.:nanawrench::You_Rock:

Actually, :You_Rock: , for taking good advice and trying it, instead of arguing why it can't be so.
Let us know what your results are David.

I replace the valve and it works great, no leaks.:nanawrench::beer:
