The QUICKCAR RACING PRODUCTS Plastic Caps and Plugs (part 64-225) cover and seal open fitting ends, port openings, and line terminations during builds, storage, and transport. They keep dirt, moisture, and debris out of threads and bores that would otherwise sit exposed on a bench or in a trailer. Builders working on fuel systems, brake lines, and AN plumbing reach for caps and plugs like these to protect machined surfaces between assembly steps. We carry them alongside the rest of our fittings, hoses, and valves, so you can match protection to whatever line and fitting size you're running.
This set ships as an each-unit item with a listed weight of 1.54 lbs and a 2.7 in dimension on the longest cap. Plastic construction handles repeated install-and-remove cycles without galling the threads or sealing surfaces underneath, which matters on aluminum AN fittings where steel covers can mar soft alloy. The caps press over male ends while the plugs seat into female ports, giving you a clean way to blank off a line you're not running yet. Color-coded and sized plastic blanks make it easy to tell at a glance which port is capped versus live, a small thing that saves time when you're chasing a leak or pressure-testing a fresh fuel circuit.
Reach for these when you're tearing down a fuel cell, storing a carburetor, or holding off a port until a sensor or line arrives. They also keep contamination out of AN plug openings and capped lines during paint, media blasting, or long-term storage. If you're plumbing a fresh system, pair them with the matching AN caps and the rest of our fittings hardware to keep every open end sealed until final assembly. Stock a handful in the toolbox and you'll never blank a line with tape again.
They cover and seal open fitting ends and ports to keep dirt, moisture, and debris out of threads and machined bores. Builders use them during fuel system and brake line assembly, storage, and transport, and to blank off ports that aren't connected to a line yet.
Plastic blanks press on and pull off without galling soft aluminum sealing surfaces, which is why many builders prefer them over steel covers on AN hardware. They handle repeated install-and-remove cycles and won't mar the cone or threads underneath.
