10AN Bulkhead Adapter Black Male Male

The REDHORSE PERFORMANCE 10AN Bulkhead Adapter Black Male Male is a straight-port aluminum bulkhead fitting designed for high-pressure fluid systems requiring secure, leak-free connections. This 10 AN male-to-male configuration allows two -10 AN hose lines to connect through a panel, bulkhead, or firewall while maintaining the integrity of pressurized circuits. Black anodized aluminum construction provides corrosion resistance and durability in demanding environments, from high-performance automotive fuel and coolant systems to custom hydraulic installations.

The straight-port design minimizes turbulence and pressure drop compared to 90-degree configurations, making it ideal where flow efficiency matters. At 10 AN size, this fitting handles the flow rates and pressures typical of modern fuel injection systems, supercharger cooling loops, and transmission cooler circuits. The black anodized finish resists oxidation and corrosion from moisture and salt exposure, extending service life in vehicles stored outdoors or operated in harsh climates. Each fitting is machined to precise tolerances to ensure proper sealing when torqued to manufacturer specifications with appropriate thread-sealant compounds.

This adapter serves builders of custom fuel systems, transmission oil coolers, and closed-loop cooling setups who need to route lines through engine compartment walls or frame members. It's essential for anyone upgrading to AN-sized braided hose systems from OEM rubber lines, providing a cleaner appearance and superior vibration isolation. The bulkhead configuration allows one-handed access from outside the panel while the internal threads anchor securely, eliminating the need for external bracing or backup wrenches in tight spaces. Compatible with standard -10 AN male fittings and hoses across automotive, marine, and industrial fluid transfer applications.
