Yes, it was compatible with my 3/4" O GMC rear AC line. Actually, it's doing quite well, and it's still holding its R- rating a month later. Charged with 134a and able to generate cold air. Because the sleeve is a precise fit, I had to go over the outside edge of the end with sandpaper to remove the burr. It meets my expectations.
Packages should include instructions.
I'm not sure, but I'd suggest measuring the pipe where you'll be installing the cap with a wrench and using that as a guide.
Selected User Reviews For Dorman 800-996 Aluminum Line Block Off For 3/4 Line
I found the split in the line and cut the lines within 12" of the T. Before cutting the lines, I had a local shop evacuate the A/C system and perform a vacuum test before repressurizing it. Since then, the air conditioner has been blasting icy cold! This blocker has made me very happy. Thread locker was used on the threads, and PAG 46 refrigerant oil was used to lubricate the o-ring. To ensure a perfect fit, use rings. Torque wrenches were also used to ensure that the bolts were not overtightened. Getting the proper diameter fitting was the most difficult part.
I resurrected a 1995 Chevrolet G20 van with rear ac leaks. Ensure that you use a good tube cutter, that the ends are deburred, and that any debris is removed. A small shop vac is what I prefer to use. Install the suction line as close to the compressor as possible, and the liquid line as close to the condenser T as possible. Clean the outside of the tube with copper wool. Lubricate the tube with the oil that your system requires, such as pag46 or pag150. Also, thoroughly lubricate the green rubber seal. Do not overtighten these; the instructions only call for 18 ft pounds of torque, and the threads aren't designed to withstand the same pressure as the green seals. I installed these in a few hours, vaccumed the system down, closed the valves for an hour, and there was no vaccumm rise. I recharged and injected oil loss, and the system is running fine. br>br>I'm not sure how long they'll last. However, it should buy you a season or two of free time. If you want to permanently block off the rear ac, pinch braze the tube ends is always a good idea.
It does exactly what it claims. To get the parts to fit together, I had to smooth off the burr from the tubing cutter, which resulted in a nice tight fit (3/4").
It works on aluminum AC lines, according to the product website. This isn't the right thread for my needs. A return attempt was made. Company turns a blind eye.
It worked perfectly and there have been no leaks since it was installed over the winter. It's simple to cap a line with this, and I'd buy it again.
Immediately after installation, it began to leak.
It did exactly what it was supposed to do.
