Mtsooning R134A Refrigerant AC Valve Core Remover & Installer Tool Set — Red/Blue High & Low Pressure, 40 Spare Cores

Mtsooning R134A Refrigerant AC valve core remover and installer set is a complete tool kit designed to remove, replace and secure R134A service valve cores with minimal refrigerant loss.

If you service car air conditioning systems or perform HVAC maintenance, this kit bundles the most common fittings and replacement cores so you can work faster and cleaner. The set includes separate high- and low-pressure quick couplers, heavy-duty valve core removers, a supply of R134A cores and adapter caps — all built to minimize leaks and simplify swaps on compatible compressors and service ports.

How do the high- and low-pressure couplers make service easier?

The kit includes color-coded quick couplers sized for standard automotive service: a red 16mm ID high-pressure coupler and a blue 13mm ID low-pressure coupler. These let you attach and detach without spilling refrigerant when used correctly and with a compatible connector.

• Red high-pressure coupler (16mm ID) for discharge-side connections
• Blue low-pressure coupler (13mm ID) for suction-side connections
• Quarter-turn brass ball valves reduce uncontrolled gas escape during swaps
• Anti-slip body design for secure handling under pressure

What construction features prevent refrigerant leakage?

The tools are engineered from brass and stainless steel to withstand repeated use and resist corrosion from refrigerants and oils. A reinforced stainless steel valve rod holds valve cores firmly, while the quarter-turn valve stops flow when you’re positioning or removing cores.

• Stainless steel valve rod for strong suction and stable core retention
• Brass body with aluminum alloy valve components for durability
• Quarter-turn ball valve for near-zero gas loss during operation
• Anti-slip grip reduces accidental slips that could open the valve

Which parts are included and how many spare cores come with the kit?

This comprehensive package supplies both the tools and spare consumables you’ll use most often during on-vehicle service. You get multiple remover/installer tools plus a range of replacement valve cores and caps to finish several jobs without restocking.

• 2 R134A valve core remover/installer tools (1 high-pressure, 1 low-pressure)
• 2 separate valve core removers for faster swapping
• 20 R134A valve cores and 20 5V1 valve cores as spares
• 9 service port caps to protect ports after maintenance

Will this kit fit my vehicle’s AC system?

Compatibility varies by vehicle and compressor connector; not all cars use the same valve core type or service port geometry. Confirm your car’s valve type (R134A vs older R12 fittings) and check with your dealer or service manual before purchasing to avoid incompatibility.

• Check your vehicle’s service port size and refrigerant type first
• Verify compressor connector compatibility with R134A quick couplers
• Older R12 systems may require different fittings or adapters
• Use included caps to protect ports when not in use

Who this is for: Technicians, independent mechanics and DIY car owners who regularly service automotive AC systems and need a reliable, ready-made kit for valve-core replacement will benefit most. If you confirm your vehicle uses R134A service ports, this set supplies durable tools, multiple spare cores and protective caps so you can complete several jobs with minimal refrigerant loss and fewer trips for parts.
