Four Seasons 59172 Flush Gun Tool Kit

A little spendy compared to other options. It would be nice If other connection options were included. The clamp on connector isn’t suitable for some applications.

This flush kit can handle the 120 psi required because it can securely attached to an AC line without releasing any back pressure. I did not use mine very much. I had it three years. All of the parts held pressure right out of the box. The bottle and valve are high quality. After three years the rubber seal that attaches to the AC line was starting to crack, and I broke the plastic regulator by twisting it the wrong way. I am buying another one. I wonder if Four Seasons sells the rubber seal separately? I could probably bypass the regulator, but it's a good safety feature. I will season the new rubber seal with mineral oil before and I after each flush.

Great flusher with high quality parts.I used it to first flush the ac system and then i also I used it to inject compressor oil into the system(had to buy extra parts). I was then able to vacuum out all moisture and air with a pump. Really nice quality.

use it once and it work great

Works well. Kinda hard to get attached to some lines especially smaller ones.

have used this on a couple of cars now. Works great.

Works great for flushing a contaminated AC system.

Great product , well pleased
