90 Deg #4 Gau. Fitting

The 90 Deg #4 Gau. Fitting by EARLS is a precision hydraulic adapter engineered for high-pressure fluid systems common in tactical vehicles, aerospace platforms, and specialized military equipment. This compact right-angle fitting serves as a critical junction point in brake lines, fuel systems, and cooling circuits where space constraints or routing geometry demands a 90-degree directional change. Field-proven across decades of law enforcement and military operations, this component ensures reliable pressure transfer without compromise to system integrity or flow efficiency.

Manufactured to EARLS' exacting standards, the 90 Deg #4 Gau. Fitting utilizes a number-four gauge designation, corresponding to a 1/4-inch SAE thread size—the industry standard for mid-pressure hydraulic applications. The elbow configuration allows tube or hose assembly to transition direction cleanly, minimizing stress concentration and vibration-induced fatigue at connection points. Weighing just 0.07 pounds with compact dimensions of 1.25 x 0.95 x 3.3 inches, this fitting integrates seamlessly into tight-quarters installations found in tactical platforms, armored vehicles, and portable hydraulic systems where weight and footprint directly impact operational capability.

Technicians maintaining government-issue vehicles, military transport fleets, and specialized tactical equipment routinely specify EARLS fittings for their durability under extreme vibration and pressure cycling. This 90-degree adapter is ideal for suspension upgrades, brake system retrofits, and custom hydraulic fabrication work where OEM routing proves impractical. Installation requires basic SAE thread compatibility verification and proper torque application to prevent leakage—critical in systems where fluid loss compromises braking response or vehicle stability.
