Does auto air conditioner Stop leak work?
AC stop leak sealers can work to stop small pinhole leaks in the AC pipes. It is not proven that they can stop leaks around O-rings or shaft seals, which is much more common than pinhole leaks in AC systems.
How to charge an R12 to r12a refrigerant?
It’s basically the same procedure as adding R12 except you must screw on the R12-to-R12a quick-connect adapter fitting pictured below (included in the kit) to the LOW suction service port first. The adapter fitting has it’s own Schrader valve internally, so no gas will escape. The video below shows the charging procedure.
Which is better r12a or R134A AC confiusion?
You can find R134 in single can or can with pressure gauge, which is very easy to use. Make sure you use only R134a. You will need to evacuate your system only if it has gone “atmospheric” (has had a leak so bad that air and water vapor have entered the system).
Is it legal to use R12 in autos?
R12 was outlawed for use in new auto A/C systems several years ago and has since become hard to find. As far as I know it is still legal to use the stuff in older A/C systems that require it. All new A/C switched over to R134 systems right around 1990 I think.
Can you use Red Tek on an R134A air conditioner?
(A very pricey alternative to get an older system working.) If I had an R134a system like in our Trailblazers, I would use R134a to top it up. Yes, Red Tek can result in cooler temps but if I add or use Red Tek, I am limiting the ability of an air conditioning tech from working on it in the future.
Is it legal to use Red Tek r12a refrigerant system?
Technically ALL refrigerants are flammable when they are mixed with the oils in the system, so its a moot point at best. It is legal to use them in America, but technically you cant retrofit a R12 system to R12a. You first have to go to 134. (silly loophole, but worth noting).

Where is the recharge port on a Red Tek r12a?
Today I’m messing around with “Red Tek” r12a recharge kit. The high and low ports on this car seem to be mounted directly to the compressor – not in-line on the hoses that a lot of youtube video’s show.
