Review on π Detool Adjustable R134A Adapter Fittings: High-Low Quick Coupler for HVAC AC Systems & Refrigeration - 1/4 SAE Connector by Matthew Peterson
Stuck on your service ports.
Doesn't seem to fit my f250. I had to force her somehow. The low side (blue) would not sit. I thought maybe because no one tested the AC. Finally I put it on with the help of a small rubber mallet and read it. Now I can't tear off the blue page.
Pros
- Stable test results
Cons
- Not everything fits
