Russell Performance -4 AN Flare Cap (Blue)

Russell's -4 AN Flare Cap is a handy little part for custom fuel or oil line setups. It's designed to seal off a -4 AN fitting, which is common in many aftermarket fuel systems, oil coolers, or other fluid transfer lines. This cap is made from lightweight 6061-T6 aluminum, so it won't add unnecessary weight to your build.

The blue anodized finish not only looks sharp but also helps protect the aluminum from corrosion. It's precision machined to ensure a positive seal, even at the highest operating pressures you might encounter in performance applications. This fitting is a straightforward way to cap off an unused AN port or to finish a line cleanly.
