LEONTOOL AC Valve Core Removal Tool Kit — Red/Blue High & Low Pressure Couplers, Brass Quarter-Turn Shutoff

LEONTOOL AC Valve Core Removal Tool Kit is a complete brass-based set for removing and replacing high- and low-pressure Schrader valve cores on most R134a, R1234yf, and R22 automotive A/C systems without refrigerant loss.

When servicing vehicle air conditioning, a reliable valve core tool speeds the job and reduces refrigerant escape. This LEONTOOL kit combines durable brass construction, quarter-turn shutoff couplers and multiple replacement cores and O-rings so you can change valve cores on the road or in the shop with minimal mess and downtime.

How does this kit prevent refrigerant leakage during service?

The quick couplers use a side-mounted ball valve that opens and closes with a quarter-turn, letting you engage or isolate the line while removing a valve core. Integrated O-rings and the precision brass coupler body create a tight seal that minimizes refrigerant loss when connecting or disconnecting.

• Quarter-turn side ball valve to isolate refrigerant flow
• Integrated O-rings for a hermetic seal during core removal
• Precision brass fittings reduce wear and maintain a secure connection

Which refrigerant systems and valve cores will this tool work with?

The kit is compatible with most standard Schrader-style automotive valve cores used in R134a, R1234yf and R22 systems, allowing broad use across modern and older vehicles. It does not support valve cores built to JRA specifications, so check the vehicle’s valve type if unsure.

• Designed for R134a, R1234yf and R22 Schrader valve cores
• Includes replacement R134a and R22 cores in the kit
• Not compatible with JRA-specification core designs

What parts are included and what materials are used?

The set contains two valve core removers for high and low pressure, two quick couplers (high-pressure red, low-pressure blue), spare valve cores and extra O-rings so you can complete multiple repairs without scavenging parts. Components are primarily brass for corrosion resistance and impact durability.

• 2 brass R134a valve core removers (high and low pressure)
• Red high-pressure coupler (16 mm I.D.) and blue low-pressure coupler (13 mm I.D.)
• 2 R134a cores, 2 R22 cores, plus 2 large and 2 small O-rings

How easy is this tool to use during a quick roadside repair?

Compact and straightforward, the couplers attach to the service port, you close the side ball valve, remove the old core with the included remover, then install the replacement core and reopen the valve. The color-coded couplers and plug-and-play parts make the process intuitive for technicians and DIYers alike.

• Color-coded red/blue couplers for immediate high/low identification
• Simple quarter-turn valve operation for fast isolation
• Enough spare parts included for rapid field repairs

Who this is for: This LEONTOOL kit is intended for automotive technicians, fleet maintenance crews and experienced DIYers who need a durable, portable valve core removal solution compatible with common refrigerants. It’s ideal when you want to replace valve cores quickly while minimizing refrigerant loss and avoiding repeated trips to buy parts.
