Lichamp Vacuum-Rated Valve Core Removal Tool — 5/16" Female to 1/4" Male Flare, 20 Micron Vacuum, Solid Brass

Lichamp’s vacuum-rated valve core removal tool lets technicians remove and replace service cores under deep vacuum conditions—compatible with R410A, R22 and R32 systems.

Compact and precision-machined from solid brass, this valve core tool combines two common flare sizes (5/16" female and 1/4" male) with a vacuum rating to 20 microns. It’s designed to maintain a secure seal during evacuation and charging so you can service refrigeration and HVAC equipment while minimizing refrigerant loss. Built features—like a knurled non-slip grip, magnetic base, and adjustable valve stem—help speed up routine maintenance in tight or vertical spaces.

How does this tool protect a vacuum during valve core removal?

The tool’s internal geometry and tight brass machining provide a leak-resistant path while you extract or insert a valve core, enabling operations down to 20 microns. That vacuum capability reduces the risk of moisture and air re-entry during evacuation and recovery.

• Deep vacuum rating to 20 microns for robust evacuation protection
• Precision brass seats maintain a gas-tight seal during service
• Compatible with common refrigerants to avoid cross-contamination

Which fittings and systems will this adapter work with?

It adapts between a 5/16" female flare and a 1/4" male flare, covering typical field hardware on many HVAC and refrigeration systems. The tool is intended for stationary refrigeration and HVAC service equipment, not for automotive A/C applications.

• 5/16" female flare to 1/4" male flare for broad compatibility
• Works with R410A, R22 and R32 service lines and valves
• Not recommended for automotive air-conditioning systems

What user features speed up on-site repairs?

Ergonomic details reduce time and fumbling in the field: a knurled grip for positive handling, a magnetic base to hold the tool on metal surfaces, and an adjustable valve stem to reach recessed cores. These elements lower repetitive strain and help maintain accuracy in confined spaces.

• Non-slip knurled grip for precise control during core extraction
• Integrated magnet keeps the tool accessible on metal service carts or panels
• Adjustable stem reaches recessed or awkward valve placements

How durable and service-friendly is the construction?

Made from solid brass and precision-machined, the tool resists galling and provides smooth actuation for repeated use. The design prioritizes long-term reliability and straightforward operation so technicians can trust it during routine maintenance cycles.

• Solid brass body for corrosion resistance and long life
• Fine machining for smooth core removal without damaging valve seats
• Simple, tool-free operation for fast field servicing

Who is this for? HVAC and refrigeration technicians who need a reliable valve core removal adapter that supports deep vacuum procedures will value this tool. It’s suited to service contractors, maintenance teams, and shop technicians working on commercial and residential HVAC and refrigeration systems using R410A, R22, or R32 refrigerants. If you require automotive A/C service adapters, choose a tool specifically rated for that application instead.
