Review on 🧃 FJC 2734 R134A Refrigerant Oil Injector by Justin Albright

I had high hopes for this unit because the price was too good. For the money you get a really solid injector tank that looks like a lifetime purchase. The only thing that kills is that out of the box you'll find a lot of burrs and some metal shavings from the manufacturing process where the threads were cut. In an AC system, this will inevitably lead to failure. When these burrs are introduced into the AC system, they block the valve and render the system unusable. Once you've done that, you'll need to grind off the burrs on BOTH thread faces, rinse, and put in the oven. Make sure it's smooth and doesn't cut you. Mine literally made me bleed. Then grab it, because otherwise it's a great set.
