Cone Male 45 Degree SAE Flare Fitting
Mack

The Cone Male 45 Degree SAE Flare Fitting is a precision hydraulic and fuel line connector engineered for robust, leak-free joints. It features a 45-degree flare angle that creates a strong, pressure-tolerant seat when mated with the corresponding SAE flare female component. Made from corrosion-resistant materials, the fitting maintains integrity under elevated temperatures and fluctuating pressures common in braking, fuel, and hydraulic systems. The design supports rapid assembly with standard torque specifications, facilitating reliable service in field or shop environments. Its compatibility with copper and compatible alloy lines makes it versatile for multiple heavy-duty applications, while the tight flare seating minimizes risk of leaks during extension or vibration. Proper assembly and seating are essential to maintaining brake performance and line integrity over time. Source One Parts Center.
