Review on R410A R22 Valve Core Remover Installer Tool | Dual Size SAE 1/4 & 5/16 Port | Compatible for R404A R407C R134A R12 R32 HVAC System | Includes 10PCS 5v1 Valve Cores and Double Head Valve Core Remover by Justin Live
Leaks like a sieve
Completely unusable for its intended purpose right out of the box. Pay for the best brands like Appion and the like and the products get better. The few dollars saved on this unit are more than offset by the cost of refrigerant leaks. Luckily I tested nitrogen first!
- Consistent test results
- Good, but not great
