VELQUAI HVAC Valve Core Removal Tool — Dual 1/4" & 5/16" Connectors, Vacuum-Rated 20 Micron, Includes Spare Cores

VELQUAI's HVAC Valve Core Removal Tool is a dual-ended, vacuum-rated installer that lets you remove and install 1/4" and 5/16" valve cores on multiple refrigerants without shutting down the system.

This compact tool combines a 1/4" and 5/16" connector, a precision sealing system and an adjustable clamping tip so technicians can change valve cores quickly while maintaining service-port pressure or performing vacuum tests. Supplied with spare valve cores, the kit is engineered for compatibility with legacy and newer refrigerants and built to hold cores securely during service in tight spaces.

How does this tool handle different refrigerants and systems?

The VELQUAI tool is sized and sealed to work across a broad range of refrigerants from older R22/R12 systems to modern blends like R410A, R32 and R1234yf. Its materials and valve interface are selected to tolerate standard HVAC service environments and common refrigerant chemistries.

• Dual connectors: 1/4" and 5/16" service port compatibility.
• Works with R22, R134a, R410A, R32, R1234yf and other common refrigerants.
• Includes 12 replacement valve cores for field swaps.

What keeps the system sealed during core removal or installation?

A precision double O-ring and a ball-valve seal lock the service port while the core is being changed, minimizing refrigerant exposure. This configuration permits pressure or vacuum checks without removing the tool, allowing technicians to confirm system integrity on the spot.

• Double O-ring plus ball-valve sealing for secure isolation.
• Maintains system pressure for accurate leak or vacuum testing.
• Reduces refrigerant loss compared to unsuited tools.

How does the tool improve speed and reliability during service?

The magnetic end cap holds valve cores in place while the adjustable clamping mechanism adapts to different core sizes and brands. The result is faster swaps, fewer dropped parts and consistent engagement even in confined or elevated locations.

• Top magnetic cap secures cores for one-handed handling.
• Adjustable clamping tip rotates to fit varying core profiles.
• Designed for quick, repeatable core removal and installation.

Can I use this tool for testing and repairs in tight spaces?

Yes — the tool's slim, dual-ended design and adjustable clamping make it practical for cramped cabinets, rooftop units and automotive service ports. Its vacuum-rated performance supports professional testing procedures without bulky adapters.

• Compact footprint fits narrow service access points.
• 20-micron vacuum rating suitable for standard evacuation checks.
• No need for extensive disassembly to replace single valve cores.

Who this is for: HVAC technicians, refrigeration service professionals and trained maintenance staff who need a dependable valve core removal and installation solution that supports a wide range of refrigerants and service port sizes. It’s useful for field service, shop repairs and preventive maintenance where controlled, leak-minimizing core changes and quick pressure or vacuum testing improve job efficiency.
