LEONTOOL AC Valve Core Removal Tool Kit — High & Low Pressure, Brass with Quarter‑Turn Leak‑Sealing Valves

LEONTOOL AC Valve Core Removal Tool Kit is a durable brass repair set that lets you safely remove and replace high- and low-pressure A/C valve cores for R134a, R1234yf and R22 systems without refrigerant loss.

Whether you're a professional technician or a DIYer servicing vehicle air conditioning, this compact kit groups the tools needed to swap valve cores quickly and securely. It combines solid brass construction, integrated O-rings, and quarter-turn ball valves to prevent refrigerant leaks while you work. The kit's color-coded quick couplers and multiple replacement cores make same-job repairs faster and reduce trips for parts.

How does this tool prevent refrigerant leakage while changing valve cores?

The LEONTOOL kit uses side-mounted ball valves that open and close with a quarter-turn to stop refrigerant flow during service. Integrated O-rings and precisely fitted couplers create a hermetic seal so the system remains closed while you extract or insert a core.

• Quarter-turn ball valve isolates pressure instantly.
• Integrated large and small O-rings for leak-free sealing.
• Brass body resists deformation for consistent sealing under pressure.

Which refrigerant systems and valve cores are compatible?

This set is designed to work with the common Schrader-style valve cores used in R134a, R1234yf and R22 automotive A/C systems. It includes multiple replacement cores and color-coded couplers to match high- and low-pressure ports, but it does not support JRA-specification valve cores.

• Compatible with most standard Schrader valve cores for R134a, R1234yf and R22.
• Includes both high-pressure (red) and low-pressure (blue) quick couplers.
• Not compatible with JRA-spec valve cores—check your vehicle's specification.

What comes in the kit and what materials are used?

The LEONTOOL kit contains two valve core removers, two couplers, two R134a cores, two R22 cores, and sets of O-rings sized for high and low ports. Components are mainly brass for corrosion resistance and mechanical strength so they stay true to size during repeated use.

• 2x R134a valve core removers (high and low), 2x R1234yf couplers.
• 2x R134a valve cores, 2x R22 valve cores, plus 2 large and 2 small O-rings.
• Mainly brass construction: anti-rust, wear resistant and impact resistant.

How does the kit speed up on-vehicle service tasks?

Color-coded couplers and pre-supplied replacement cores let you swap valve cores without running back to the parts bin. The quick coupler diameters match common service fittings so connection and replacement are straightforward, reducing downtime.

• Red high-pressure coupler (16 mm I.D.) and blue low-pressure coupler (13 mm I.D.).
• On-tool ball valves let you shut system pressure off immediately.
• Spare cores and O-rings included to finish most single-vehicle jobs in one visit.

Who is this kit for? The LEONTOOL AC Valve Core Removal Tool Kit is aimed at automotive A/C technicians, fleet maintenance teams, and experienced DIYers who need a reliable, leak-minimizing way to change valve cores on R134a, R1234yf and R22 systems. If you regularly service passenger cars, trucks, or light commercial vehicles and want brass-built durability, clear high/low identification, and enough spare parts to finish common repairs, this kit is a practical addition to your toolbox. If your vehicle uses JRA-spec valve cores, confirm compatibility before purchase.
