31-Piece A/C Valve Core And Cap Kit For R12/R134A Automotive Systems

This all-in-one kit contains assorted A/C valve cores and service port caps, fully stocked to handle most automotive air conditioning repair jobs. Replace worn, corroded or leaking valve cores and missing caps in one set, ideal for DIY car owners and professional auto technicians.

Precision engineered to work with both classic R12 and modern R134A automotive A/C systems. Fits high-pressure and low-pressure service ports on most cars, trucks and SUVs, perfect for A/C leak repair, refrigerant service and system maintenance.

Made of high-strength brass with durable rubber sealing gaskets. Resists corrosion, high pressure and temperature fluctuations under the hood. Delivers tight sealing to prevent refrigerant leakage, maintain stable A/C pressure and keep your cooling system running efficiently.

The matched A/C caps feature built-in sealing rings. They shield service ports from dust, water, debris and oxidation when not in use, reducing premature valve core failure and avoiding costly A/C system leaks. Color-coded for quick identification of high/low pressure ports.

Comes with a divided plastic storage box to organize all parts neatly, preventing loss and convenient for carrying in toolboxes or vehicle glove boxes. Simple to install and remove with standard A/C valve core tools, saving your time on auto air conditioning service.
