JKLESA HVAC Valve Core Removal Tool — Dual-Head 1/4" & 5/16", Vacuum-Rated 20 Microns for R410A/R22

JKLESA's dual-head HVAC valve core removal tool quickly removes and installs 1/4" and 5/16" valve cores and is vacuum-rated to 20 microns for reliable system evacuation.

This compact, heavy-duty tool combines two common flare nut fittings in a single body so technicians can service a wide range of refrigerant lines without swapping tools. Built for refrigeration and air conditioning work with refrigerants such as R410A, R22, R32, R404A and R407C, it speeds up core replacements, leak response, and evacuation while minimizing downtime and refrigerant loss.

How does this tool save time on a service call?

Because the rear end integrates both 1/4" and 5/16" flare fittings, you can adapt to most service ports without changing tools. The dual-head design lets you switch sizes quickly, reducing trips to the truck and simplifying field workflow.

• Built-in 1/4" and 5/16" flare nut fittings for immediate compatibility
• One-handed core removal and installation speeds repairs
• Fewer tool swaps means faster diagnosis and service completion

Can it maintain a proper vacuum and protect the system?

This valve core tool is vacuum-rated to 20 microns, enabling technicians to achieve a deep evacuation when preparing systems for charge or after repairs. That level of vacuum helps remove moisture and non-condensables, improving system integrity without introducing additional fittings or adapters.

• 20-micron vacuum rating supports thorough evacuation procedures
• Designed for high-pressure refrigerants including R410A
• Reduces refrigerant loss during core removal and replacement

What makes the JKLESA tool durable for daily HVAC work?

The body and handle are machined from high-strength metal to resist impact and torque, avoiding the failure points common to plastic components. This construction survives cramped valve locations and repeated use, delivering consistent performance throughout many service cycles.

• Metal body and key handle for superior impact resistance
• Designed to withstand torque in tight spaces without cracking
• Long service life reduces tool replacement costs

Which service tasks is this tool best suited for?

It’s made for routine maintenance, emergency repairs, evacuation and commissioning. Whether you’re swapping cores during a preventive check, responding to a field leak, or evacuating a system before a recharge, the JKLESA dual valve core remover handles those core duties efficiently.

• Seasonal valve core replacement and preventive maintenance
• Emergency leak repairs and quick core replacement
• System evacuation and commissioning procedures

Who is this for: HVAC/R technicians, service contractors, and maintenance teams who need a compact, dependable valve core removal tool that supports multiple flare sizes and deep vacuuming. If you frequently work with R410A, R22, R32, R404A or R407C systems and want a rugged, single-tool solution to speed field work and protect system integrity, this JKLESA dual-head core tool is designed for your toolbox.
