1/4" Mega Flow Vacuum-Rated Valve Core Removal Tool, 20 Microns Vacuum, Compatible with R22 R410A R404A, Suitable for Home AC Equipment, Essential HVAC Tools, Fast Recovery & Evacuation (1 Pack)

Vacuum-Rated Valve Core Removal Tool for 1/4 in. Safe to remove and reinstall the valve core without refrigerant leakage, even when the refrigeration system is under pressure, unvented, and in operation. Evacuating through a valve core and core depressor can reduce the potential flow of any vacuum pump to as little as 0.2CFM. The stem tip can be tightened or loosened to accommodate various valve core sizes, providing a secure grip for easy removal and installation.

• Pressure-Free Valve Core Removal & Installation - Specifically designed for HVAC, air conditioning, and refrigeration systems. Double O‑ring ball valve sealing structure isolates system pressure, allowing you to safely remove or install Schrader cores without depressurizing the system, shutting down equipment, or causing refrigerant leakage, saving time and avoiding refrigerant waste.
• Full Flow Design for Efficient Operation - By removing the valve core, the tool enables full-flow access to the system. This significantly speeds up vacuum evacuation, refrigerant recovery, and refrigerant charging processes, improving work efficiency for both professional technicians and DIY enthusiasts.
• Universal 1/4" Side Port Compatibility - This tool perfectly matches most HVAC system service ports. It is compatible with all mainstream refrigerants, including R12, R22, R410A, R32, and R404A, suitable for home/commercial air conditioners, heat pumps, refrigerators, freezers, and automotive air conditioning systems.
• Durable & User-Friendly Construction - Made of high-quality corrosion-resistant metal, the tool is built to withstand high pressure (up to 800 PSI) and deep vacuum (down to 20 microns), ensuring long-term reliability. The ergonomic knob and clear ON/OFF ball valve design make operation simple—no complex steps, even for beginners.
• Professional & Versatile Application - Ideal for HVAC technicians, auto mechanics, and DIY users. It can be used for valve core replacement, system maintenance, vacuum testing, refrigerant charging, and leak detection. A must-have tool for anyone working with refrigeration or air conditioning systems.
