Automobile air conditioning valve core disassembly tool. Red and blue color differentiation corresponds to high and low pressure interfaces. Made of aluminum alloy and brass, lightweight and durable. Anti-slip knob for single-handed operation. Deep-hole valve cores can also be easily disassembled and assembled. Suitable for top pins without damaging the pipeline. The tool kit is carried with you. Refilling refrigerant and maintenance can be completed in just 1 minute.

The car air conditioning system "goes on strike", refrigerant leakage, unstable pressure? Traditional repairs require emptying the refrigerant, which is labor-intensive and costly - this pressure-proof valve core replacement tool directly breaks through the industry's pain points!
The red and blue colors distinguish high and low pressure, compatible with 99% of car air conditioning systems: the red color precisely matches the high-pressure side pipeline of the compressor, the blue color fits the evaporator interface, the snap-on design locks instantly without the need for professional skills, and can be quickly connected. The core advantage lies in "no refrigerant discharge": during pressure operation, the valve core quickly pops open the old valve and inserts the new core, with zero leakage throughout the process. It saves the cost of refrigerant replacement and can be completed in 10 minutes, with an efficiency 5 times that of traditional methods.
The copper alloy valve body is corrosion-resistant and can withstand high pressure, the aluminum knob is anti-slip and easy to turn, with a 194g lightweight design that is comfortable to hold for a long time; the adjustable extension rod is compatible with concealed pipelines, and the 13.3mm/16.2mm dual interfaces cover the mainstream valve core specifications. Whether it's batch operations in auto repair shops or DIY emergency repairs by car owners, it is both a cost-saving and efficiency-boosting "air conditioning savior" - from now on, repairing air conditioning no longer requires waiting or waste, with just one tool to handle it!
During summer driving, the air conditioner suddenly stops working. Upon inspection, it turns out that the valve core has aged and is leaking. Most repair shops would say that "the refrigerant needs to be drained and the core replaced", which not only requires a 2-hour wait but also involves an additional cost of hundreds of yuan for refrigerant replacement? This car air conditioning pressure replacement valve tool is precisely designed to address this pain point: without draining the refrigerant, the valve core can be replaced under pressure, turning the air conditioning repair from a "major project" into a "quick and efficient ten-minute job".
Its core "leak-free refrigerant" design is derived from the precise pin-type structure: after connecting the tool to the air conditioning pipeline, rotating the knob can push open the original valve core, while the new valve core simultaneously inserts into the interface, ensuring a fully sealed and leak-free process - this means you no longer have to pay for the "draining - adding refrigerant" procedure, nor wait for the lengthy vacuuming time. What you save is not only the 200+ yuan for refrigerant replacement costs, but also half a day of repair waiting time.
The dual-color red and blue high and low pressure specifications are another highlight of this tool: the red model corresponds to the high-pressure pipeline (suitable for the compressor side, with an interface diameter of 16.2mm), and the blue model corresponds to the low-pressure pipeline (suitable for the evaporator side, with an interface diameter of 13.3mm). The snap-on quick connection design locks in place with one click, allowing beginners to easily distinguish between high and low pressure and avoid connecting the wrong part and damaging the system. The valve body is made of brass, resistant to high pressure and refrigerant corrosion, and the aluminum alloy knob has a diamond-shaped anti-slip pattern, allowing for precise force application even with gloves on; the 194g weight strikes a balance between durability and portability, making it effortless for auto repair technicians to carry it in their tool kits, and convenient for car owners to keep it in the trunk for emergencies without taking up space.
The ingenious details further demonstrate professionalism: the adjustable extension rod can be extended up to 61.5mm, easily reaching the hidden pipes deep in the engine compartment; the double-threaded interface is compatible with 95% of the valve core specifications in the market, eliminating the need for additional adapters; the total length of 123.3mm ensures both the operation distance (to avoid refrigerant freezing) and flexibility in navigating between narrow components.
Whether it's daily maintenance at auto repair shops - during batch operations, it can repair 5 more air conditioners in a day, saving over 1,000 yuan in refrigerant replacement costs per month; or for DIY emergencies by car owners - on a weekend road trip when the air conditioner leaks, you can quickly replace the valve core to restore cooling without waiting for rescue; or even for the air conditioning maintenance of trucks and construction machinery, its high-pressure tolerance can easily handle the situation.
From "draining the refrigerant with a big effort" to "replacing the valve core under pressure in just ten minutes", this tool redefines the efficiency of car air conditioning repair - saving costs, time, and worry, being both an "efficiency tool" for auto repair technicians and a "summer necessity" for car owners.
