Bulkhead Nuts Black -4 2pk

The Bulkhead Nuts Black -4 2pk from Allstar Performance are designed for use in high-pressure hydraulic and fluid systems, making them ideal for racing, industrial, and precision engineering applications. This two-pack of -4 AN (Army-Navy) bulkhead nuts ensures secure, leak-free connections in fuel systems, brake lines, and coolant circuits.

Manufactured from black anodized aluminum, these bulkhead nuts feature the -4 AN thread specification, which corresponds to a 1/4-inch tubing outer diameter in standard SAE nomenclature. The anodized finish enhances corrosion resistance and durability, while the lightweight aluminum construction is crucial in motorsports where minimizing weight is essential.

These bulkhead nuts are perfect for professional engine builders, custom fabricators, and restoration specialists, especially for applications like fuel cell installations and intercooler setups. The matched pair design ensures compatibility and consistency when replacing or upgrading dual-line systems.
