Endura Bulkhead Nut #8 Blue

The Russell Endura Bulkhead Nut #8 Blue is a precision aluminum bulkhead fitting nut engineered for high-pressure hydraulic and pneumatic systems. This #8 AN (Air Force-Navy standard) rated component features blue anodized aluminum construction, delivering corrosion resistance and reliable performance in demanding fluid transfer applications. Each nut is manufactured to exact AN specifications, ensuring proper thread engagement and leak-free connections when paired with compatible bulkhead fittings and hoses.

The #8 AN designation indicates this nut is designed for use with #8 AN bulkhead fittings, a standard sizing across aerospace, automotive, marine, and industrial hydraulic systems. The aluminum construction keeps weight minimal while the blue anodize finish provides a durable protective layer against oxidation and corrosion—particularly valuable in high-moisture or salt-air environments. Proper torque application during installation ensures the fitting maintains its seal integrity without over-tightening, which is critical for systems operating under sustained pressure.

Technicians, maintenance professionals, and system builders rely on Russell bulkhead components for repair, assembly, and upgrade work across aircraft, race car fuel and coolant systems, marine engine installations, and industrial hydraulic lines. This individual nut is ideal for replacement scenarios where a single fastener has been damaged or lost, or for custom fabrication projects requiring certified AN-standard fittings. Russell's long-standing reputation in fluid-transfer systems means this nut meets the exacting standards expected in safety-critical applications.
