Frequently Asked Questions

Does part number 30028 fit the low-pressure or high-pressure A/C port?

The 30028 is designed specifically for the low-pressure A/C service port. It threads directly onto the standard OEM low-side port fitting.

Will this cap interfere with A/C service access?

No. The cap threads off by hand in seconds, giving full access to the service port for manifold gauge connections during A/C service.

Does the cap prevent refrigerant from escaping?

The A/C port has a Schrader valve that prevents refrigerant loss regardless of the cap. The 30028 is a protective cover for that valve, not a sealing element.

Installation Instructions

  2. Twist the factory plastic cap counterclockwise to remove.
  3. Thread the Billet Technology 30028 clockwise onto the service port until snug.
  4. Do not over-tighten the cap onto the service port fitting.
  5. Verify the cap threads fully and sits flush.

Engine Covers

Engine covers and engine bay dress-up components transform the underhood appearance of street cars, show builds, and muscle car restorations by replacing factory plastic engine toppers, air cleaner assemblies, and exposed wiring with billet aluminum, carbon fiber, and anodized covers that project a finished, custom look. On modern high-performance vehicles including the Dodge Challenger, Charger, Hellcat, Trackhawk, Jeep Grand Cherokee, and Chevrolet Camaro and Corvette, factory valve covers and engine toppers are functional but visually uninspiring compared to what Billet Technology, Cordes Performance, and Anderson Composites produce for the same platforms. Classic and muscle car owners restoring small block Chevy, big block Chevy, Ford 289, 302, 390, and Chrysler 440 and HEMI engines find that chrome and polished aluminum valve covers, air cleaner kits, and timing chain covers complete the correct engine bay presentation for shows and driver quality restorations.
