R134A Can connection problem Sign In

I have a refrigerant gauge set that I need to hook up to my Toyota 2003 Corolla and bought can of R134A . I need the can valve that will hook up to the gauge hose and the can. I bought one at Advanced Auto Parts
but the threads were smaller on the gauge hose than the valve tap so they won’t connect. The man said at the parts store the threads on my gauge hose is metric. It has 1/4 opening hose on Classe 1.6 gauges
I could use a little help what I need to get for the can and the couplers to connect to my low and high side ports.

What you need is a professional shop. No good can come of that death kit you bought. If the threads don't match it is because they were made for different refrigerants.

Believe me, you can do a lot more harm than good by randomly pumping refrigerant into a system without knowing exactly how much is in it now and you can't know that without a total evacuate and weighed recharge.

Are you even sure it's a low refrigerant problem? That system only holds around a pound of refrigerant, so unless you know how much is in it how do you know how much to add? I agree with HT's suggestion to have a professional AC specialist check it out.

Been adding a can last 2 years. Holds for the summer. Small leak somewhere but the shop couldn't pin point it . Got tired of eating 100.00 deductibles.

And if you keep that up you will soon be replacing the whole system.
