#3 Bulkhead Nuts 2pk

The #3 Bulkhead Nuts 2pk by RUSSELL are essential hydraulic and pneumatic fitting components designed for professionals who demand reliability in high-pressure fluid transfer systems. These steel nuts form a leak-free seal when paired with bulkhead fittings and are widely used in aerospace, automotive, industrial hydraulics, and custom fabrication applications. A two-pack configuration ensures you have backup hardware for installation, maintenance, or system expansion without additional orders.

Manufactured from hardened steel with zinc plating, these #3 AN (3/16" – 24 thread) bulkhead nuts deliver corrosion resistance and durability in demanding environments. The zinc-plated finish protects against rust and oxidation while maintaining electrical conductivity for grounded systems. The compact size—fitting within a 2.5 x 1.65 x 4.85-inch footprint per pair—makes these nuts ideal for space-constrained installations where precision and compactness are critical. RUSSELL's established reputation for aerospace-grade fittings ensures these nuts meet strict tolerances and material standards.

Mechanics, fabricators, and system technicians benefit most from keeping spare bulkhead nuts on hand for quick repairs or system modifications. These nuts are compatible with standard AN bulkhead fittings used in fuel systems, brake lines, oil coolers, and intercooler plumbing on performance vehicles, race cars, and industrial equipment. Installation requires only a wrench or socket—no special tools needed. Whether you're building a custom fuel system, maintaining existing hydraulic lines, or stocking your shop inventory, this two-pack provides the reliability and versatility you expect from RUSSELL fittings.
