Russell Performance -4 AN Plastic Cap (10 pcs.)

These red plastic caps are designed to fit -4 AN fittings. They're made in the USA and come in a set of 10, which is handy for keeping your parts clean and protected during installation or while they're in storage. The plastic construction makes them lightweight and easy to use.

Using caps like these helps prevent dirt and debris from getting into your fuel or oil lines, which is important for a clean build. They're a simple but useful part of the assembly process, especially when you're working with sensitive fluid systems.
