🌡️ Yellow Jacket 49137 3-1/8" Red Pressure Gauge: R-22/404A/410A, 0-800 psi, Fahrenheit Measurements - Ultimate HVAC Tool Review

As an automotive enthusiast, I always want to make sure my car's engine is in top condition. Yellow Jacket 49137 Pressure Degrees has been a lifesaver for me - it's easy to install, reads pressure accurately, and helps me keep an eye on the engine's performance. As a result of using this product, I found that my car's fuel efficiency has improved significantly. The only downside is that the display is not backlit, which makes it hard to read in low light conditions.

Use this gauge to check the coolant level in your air conditioner. Attach directly to the quick release valve. No waste from long hoses.

hate to give reviews unless time has passed and actually use something in real time have this pressure gauge and use it quite often use it to check the pressure in the air conditioner To use my manifold set which eliminates a lot of potential leaks, put a 1/4" schrader adapter on it to connect to the service port on the main tool so it can be plugged in and only 1 potential leak is disconnected from the system , it was regularly at 500 psi
