The 0278335 outlet fitting is a connector designed to attach a fluid hose to the outlet port of compatible sprayer pumps. It is specifically engineered for use with SprayTech AirCoat and SprayTech ED655 Plus models. This fitting screws directly into the pump manifold or fluid section and provides a threaded or barbed connection for the high-pressure hose that leads to the spray gun. It is manufactured from durable materials such as steel or brass to withstand the high pressures generated by the pump and resist corrosion from paints and solvents. A reliable outlet fitting is essential for maintaining system pressure and preventing leaks. Over time, outlet fittings can become damaged due to overtightening, vibration, or corrosion. Threads may strip, sealing surfaces may become damaged, or the fitting may crack. A faulty fitting can cause fluid leaks, loss of pressure, and messy operation. Symptoms of a damaged outlet fitting include visible leakage at the connection, difficulty attaching the hose, or signs of corrosion. Replacing a worn or damaged outlet fitting with this genuine part restores a secure, leak-free connection. This ensures that all fluid is delivered efficiently to the gun at the correct pressure. When replacing the fitting, it is important to use thread sealant if required and to tighten to the correct torque to avoid damage. Using the correct replacement ensures proper fit and long-lasting performance.
