Drako-Myxx Valve Core Removal Tool — Dual 1/4" & 5/16" Vacuum-Rated, Double O-Ring Leak-Tight

Drako-Myxx Upgrade Vacuum-Rated Valve Core Removal Tool is a dual-size, leak-tight valve core installer/remover designed for HVAC, refrigeration, and automotive A/C systems.

This compact, vacuum-rated tool combines interchangeable 1/4" and 5/16" fittings with a secure stem and double O-ring ball valve to let technicians remove and install valve cores without losing refrigerant or compromising system integrity. Built for repeated shop use, it supports modern refrigerants including R1234yf and common legacy types so you can work across multiple systems with one convenient device.

How does this tool prevent refrigerant loss during service?

The built-in double O-ring ball valve creates a snug, leak-resistant seal so you can test and service systems while maintaining vacuum integrity. The valve closes quickly to avoid accidental discharge when the core is engaged or released.

• Vacuum-rated construction for leak-tight sealing during tests
• Double O-ring ball valve for redundant sealing
• Quick-close action to limit refrigerant escape
• Compatible with vacuum and pressure testing workflows

Which vehicle and equipment fittings are supported by the 2-size head?

The removable tip accepts both 1/4" standard service ports and an optional 5/16" adapter, so a single tool fits a broad range of HVAC, refrigeration, and automotive applications. It works with contemporary refrigerants and many legacy types used in shop and field service.

• Includes 1/4" fitting plus 5/16" interchangeability
• Compatible with R1234yf, R1234ze(E), R410, R22, R12, R407, R404, R32
• Suitable for HVAC systems, refrigerators, furnaces, and A/C service ports
• Eliminates need for multiple single-size tools in mixed fleets

How does the tool hold and release valve cores reliably?

The stem tip tightens to grip valve cores securely during removal and loosening, and it can be adjusted to accommodate different core sizes. A magnetic cap keeps spare cores close at hand so you can swap parts quickly without dropping or misplacing small components.

• Adjustable stem tip for different core dimensions
• Firm mechanical grip for one-handed core removal
• Magnetic cap stores cores safely during service
• Includes 12 replacement valve cores in the kit

What features make this tool durable and service-ready?

Designed for repeat shop use, the tool integrates robust materials with precision sealing and a magnetic cap to streamline workflow. The finish and fit resist wear while the internals maintain vacuum performance over repeated cycles.

• Robust machining and corrosion-resistant finish for longevity
• Double O-ring design preserves sealing performance
• Magnetic cap and compact size improve field ergonomics
• Kit includes 1 tool plus 12 valve cores for immediate use
