The Brake Fitting #4-3/16in Bulkhead by Longacre is a precision hydraulic adapter engineered for high-pressure brake line integration in tactical vehicles, competition platforms, and specialized military applications. This straight bulkhead fitting serves as a critical junction point where hardline brake tubing connects to distribution blocks or master cylinders, making it indispensable for operators who demand leak-free pressure integrity under demanding field conditions. Whether you're building a custom tactical platform or maintaining existing hydraulic brake systems, this fitting ensures repeatable, reliable connections that withstand vibration and thermal cycling.
Manufactured from aluminum and finished in red anodized coating, the Brake Fitting #4-3/16in Bulkhead features a 3/8-24 inverted flare male connection on one end and a 4 AN male bulkhead port on the other, enabling secure coupling between 3/16-inch hardline tubing and AN-standard distribution systems. The inverted flare design provides a mechanical seal superior to standard compression fittings, reducing the risk of weeping under sustained pressure—a critical consideration in vehicles subject to rough terrain and high-G maneuvers. Red anodizing offers corrosion resistance and thermal stability, protecting against moisture intrusion and salt-spray degradation common in forward-deployed environments.
Brake line fittings are best suited for certified technicians and experienced builders familiar with brake system pressure testing and DOT hydraulic specifications. Installation requires proper flaring tools, torque wrenches calibrated to AN fitting standards, and a clean work environment to prevent contamination. This fitting is compatible with military-grade brake systems, off-road tactical vehicles, and competition race platforms utilizing AN-specification hardline routing. Verify fitting orientation and thread engagement before pressurizing to ensure full seat contact and eliminate potential air pockets that compromise braking response.
