Drako-Myxx Vacuum-Rated Valve Core Removal Tool — Dual Size 1/4" & 5/16", Includes 12 Cores

Drako-Myxx Upgrade Vacuum-Rated Valve Core Removal Tool is a dual-size installer that removes and installs 1/4" and 5/16" valve cores while preserving system vacuum for accurate testing and charging.

When you work on air-conditioning, refrigeration, or HVAC systems you need a reliable valve core tool that fits multiple service ports, seals during vacuum testing, and holds cores securely. This Drako-Myxx set combines an installer/remover with interchangeable sizing, replaceable valve cores, and a magnetic cap so technicians can swap and stow cores without venting refrigerant or interrupting service. It’s built to work with modern refrigerants such as R1234yf and legacy types like R22.

How does the dual-size design simplify field repairs?

The integrated 1/4" and optional 5/16" fittings let you switch between common service ports without carrying two separate tools. A threaded interchange means quick changeover on the job, reducing time and tool clutter in your bag. The stem tip is adjustable so it can grip slightly different core profiles for consistent installation.

• Two fittings cover standard 1/4" and larger 5/16" service ports
• Quick thread swap avoids tool change during jobs
• Stem tip tightens/loosens to accommodate core variations

Will this tool keep systems sealed for vacuum testing?

Yes — the tool uses a double O-ring ball valve seal engineered to provide a leak-tight closure so you can evacuate and verify a system without introducing contaminants. The vacuum-rated valve prevents loss of vacuum during handling and ensures accurate leak checks before charging refrigerant. That reliable seal reduces repeat work and helps maintain system integrity.

• Double O-ring ball valve for improved sealing
• Maintains vacuum during testing and servicing
• Reduces risk of contamination before refrigerant charging

How does the kit help you handle valve cores safely and quickly?

The kit contains a dedicated valve core remover/installer and 12 replacement valve cores so you have spares on hand. The tool’s stem tip secures cores firmly for easy extraction or installation without dropping or damaging the part. A magnetic cap gives a convenient place to hold removed cores during service, minimizing lost pieces and the need to stop the system and vent refrigerant.

• Includes 1 remover/installer and 12 valve cores
• Stem tip grips cores securely for clean removal and install
• Magnetic cap holds cores during service for faster workflow
