The Brake Fitting w/Tab #4-3/16in Bulkhead (SKU: LON52-45288) is a precision hydraulic line adapter engineered for high-pressure brake systems in tactical vehicles, off-road platforms, and race applications where reliability under extreme conditions is non-negotiable. This Longacre bulkhead fitting serves operators and technicians who demand fail-safe connections in systems operating under sustained hydraulic stress. The tab-style mounting design enables secure installation in confined engine bays and custom fabrication scenarios where traditional fittings cannot accommodate frame geometry.
Constructed from red anodized aluminum, this bulkhead fitting features a straight 3/8-24 inverted flare male connection paired with a 4 AN male bulkhead outlet, designed to interface with 3/16-inch hardline tubing at maximum working pressures. The inverted flare male end provides a sealed connection without additional sealing washers, reducing assembly complexity and potential leak points in mission-critical brake circuits. Red anodizing offers both corrosion resistance and visual identification in complex hydraulic system layouts, while the tab-mount design distributes load across the frame structure rather than relying solely on fitting thread engagement. This geometry transfer minimizes vibration-induced loosening and extends component service life in vehicles subjected to rough terrain or high-G maneuvering.
Mechanics, fleet technicians, and performance vehicle builders specify this fitting for custom brake line runs, dual-circuit system reconfiguration, and retrofits where OEM hardline routing proves incompatible with upgraded brake packages or suspension modifications. The compact 4.15 x 1.4 x 5.45-inch envelope fits tight engine compartments without sacrificing structural integrity or access to adjacent components. Installation requires standard wrench flats and a quality threadlocker to ensure the tab remains secure under hydraulic pulsation and thermal cycling. Verify hardline compatibility and working pressure ratings before deployment in safety-critical systems; this fitting pairs seamlessly with DOT-approved brake fluid and standard aviation-spec hardline tubing.
