#3 90 St. Bulkhead Fit.

The #3 90 Degree Bulkhead Fitting is a precision steel hydraulic adapter designed for high-reliability fluid line connections in demanding tactical, industrial, and equipment applications. This 3 AN male-to-male bulkhead fitting delivers secure, leak-resistant joints in systems requiring compact, right-angle port orientation where space constraints or line routing necessitate 90-degree geometry.

Manufactured from hardened steel with zinc plating, this bulkhead fitting resists corrosion across variable environments—critical for vehicles, equipment, and systems exposed to moisture, salt spray, or temperature cycling. The 3 AN thread specification matches standard military and industrial hydraulic systems, ensuring compatibility with existing manifolds, cylinders, and hose assemblies rated for AN port connections. Zinc plating provides a durable barrier while maintaining the precision tolerances required for consistent seal integrity across pressure cycles.

Field technicians, equipment maintenance crews, and systems integrators rely on 90-degree bulkhead fittings to reconfigure hydraulic layouts without requiring custom adapters or compromising line routing efficiency. The male-to-male configuration accommodates female threaded ports on both sides, making it ideal for manifold-to-manifold connections, pump bypass lines, and return-line circuits where directional changes optimize component packaging and system clearance.

Sold individually, this single fitting enables point repairs or system upgrades without excess inventory. Its compact form factor (1.85 × 0.55 × 2.95 inches) fits tight mechanical spaces typical of vehicular or portable equipment hydraulics. For systems where pressure spikes, vibration, or thermal stress demand proven connection reliability, the steel-and-zinc construction and bulkhead design eliminate port leakage risk inherent in straight adapters under dynamic loads.
