Review on ๐ง Mastercool 82375 R134A Oil Injector: Essential Silver Accessory for Seamless AC Maintenance by John Bailey
The easy way to add products to your air conditioner
Very good quality. The valve works and is also of good quality. The body is machined, the thread is clean. This summer I had no problem using this item on several car air conditioners. I would recommend it to anyone who needs a way to put oil in the air conditioner. On one car, when I didn't have gauges with me, I just used a can of 134a to force oil into the system. That's how it worked great.
- Sturdy construction
- Expensive
