Russell Performance -4 AN Bulkhead Nuts 7/16in -20 Thread Size (Blue)

When you're setting up a custom fuel or oil system, you'll often need to pass a hose or hardline through a firewall or a panel. That's where a bulkhead fitting like this one comes in. This particular bulkhead nut from Russell is designed to work with -4 AN fittings and has a 7/16 inch -20 thread size, making it suitable for many common components like fuel pumps or oil pumps.

It's precision machined from 6061-T6 aluminum, which keeps the weight down while still offering a strong connection. The blue anodized finish not only looks sharp but also helps protect the aluminum. This fitting is built to ensure a positive seal, even at maximum operating pressures, so you can be confident in your fluid system's integrity.
