Ywdiml Car AC Valve Core Caps, 2PCS R134a Leakproof Vehicle Air Conditioning System Repair Charging Port Covers Replacement Kit, High Low Side Automotive Pressure Valve Cap, Universal Fit

• High-Quality Materials: The valve core cover for automotive air conditioning systems is meticulously crafted from plastic and rubber materials, combining durability with flexibility. The plastic component possesses a robust texture capable of withstanding daily friction and impacts, while the rubber element offers excellent elasticity to ensure a tight seal around the air conditioning filling port. This combination enables the valve core cover to function reliably.
• Wide Compatibility: This valve core cap offers exceptional adaptability, fitting the majority of vehicles on the market, including saloon cars, off-road vehicles, vans, lorries, SUVs, MPVs, and more. It is also compatible with most R134a refrigerant systems, featuring high-pressure (H) dimensions of approximately 0.71 x 0.37 x 0.37 inches and low-pressure (L) dimensions of approximately 0.59 x 0.41 x 0.31 inches.
• Convenient Installation: Fitting the valve core caps is straightforward. First, accurately locate the low-pressure and high-pressure ports on the air conditioning system's charging point. Next, clean the charging port. Finally, secure the corresponding valve cap in place. Clear markings on the caps indicate "L" for low-pressure and "H" for high-pressure ports, enabling swift identification even for first-time users.
• Leak Prevention: The valve cap incorporates an internal O-ring seal structure, providing critical protection. On one hand, it effectively prevents refrigerant leakage, contributing to stable cooling performance of the air conditioning system. On the other hand, it strongly blocks dust from entering the filling port, effectively preventing clogging of the service access point. This maintains internal cleanliness of the air conditioning system, supporting its sustained efficient operation.
• Practical Packaging: The product packaging contains two automotive air conditioning valve caps – one for the low-pressure port and one for the high-pressure port – meeting everyday requirements. Compact in size, the valve caps are easy to store and carry, fitting neatly into toolboxes or storage bags for convenient and practical use.
