Straight Bulkhead Adapte -12AN

The Straight Bulkhead Adapter -12AN is a precision hydraulic and pneumatic fitting designed for applications requiring a secure, leak-free connection through a panel or bulkhead wall. This adapter serves as an essential component in high-performance fuel systems, hydraulic lines, and pneumatic circuits where space is limited and reliability is non-negotiable. Whether you're building a custom automotive fuel system, assembling hydraulic brake lines, or configuring pneumatic equipment, this fitting provides the straightforward connection geometry needed to maintain system integrity under pressure.

Machined from aircraft-grade aluminum and finished in black anodize, the Straight Bulkhead Adapter -12AN features dual 12 AN male threads that enable installation on both sides of a barrier wall. The anodized coating provides corrosion resistance and durability in both engine bay and external environments, while the aluminum construction keeps weight minimal without sacrificing structural integrity. The straight flow design eliminates unnecessary bends that can cause pressure drops, turbulence, or component stress—critical for maintaining system efficiency in fuel delivery, cooling circuits, and pneumatic applications.

This fitting is ideal for fabricators, race teams, and enthusiasts who demand professional-grade components for custom builds. Installation is straightforward: thread one end through your bulkhead opening, then connect lines or adapters on both sides using standard -12AN fittings and a wrench. Compatible with all 12 AN JIC (Joint Industry Council) hoses and adapters, this component integrates seamlessly into existing modular fuel systems, hydraulic layouts, and pneumatic networks where bulkhead passage is required.
