AC Charging Port Cap Kit

This kit supplies ten replacement caps for automotive air-conditioning service ports. Five caps fit the low-pressure side and five fit the high-pressure side, covering both port sizes found on most vehicles. The parts are moulded from ABS plastic for impact resistance and direct-fit replacement of worn or leaking originals. They suit DIY maintainers and professional technicians who need a ready supply of sealing caps.

Check Port Sizes Before Fitting

Verify that the low-side port on your vehicle measures 13 mm inner diameter and 15 mm outer diameter, and that the high-side port measures 16 mm inner diameter and 19 mm outer diameter. The caps are 20 mm long overall, so confirm there is enough clearance around each service valve. The parts are universal for most cars, but port dimensions can vary by manufacturer and model year.

Sealing Performance in Service Use

The caps seat over the valve stems to block dust and debris from entering the charging ports during storage or after refrigerant service. ABS plastic withstands under-bonnet temperatures and resists cracking from vibration or accidental impact. No lubricant or thread sealant is required; the caps press on and stay in place through normal heating and cooling cycles.

Questions about this item

What comes in the package and do I need any extra tools or parts?

The box contains ten caps — five low-pressure caps with a 13 mm inner diameter and five high-pressure caps with a 16 mm inner diameter. They are direct replacements and no additional tools or parts are required for installation.

How do I know which cap goes on the low-pressure port and which goes on the high-pressure port?

The low-pressure caps have a 13 mm inner diameter and 15 mm outer diameter, while the high-pressure caps have a 16 mm inner diameter and 19 mm outer diameter. Match each cap to the corresponding port size on your vehicle.

Will these caps actually stop dust and debris from getting into the charging ports once fitted?

Yes — they seat over the valve stems to create a barrier that keeps dust and particles out of the 13 mm and 16 mm charging ports, helping prevent blockages during service and everyday use.
