The Graco 805077 Bypass Tube is a return line used in Graco airless paint sprayers to redirect paint from the prime/bypass valve back to the container during priming.
The Graco 805077 Bypass Tube is used in several professional Graco airless paint sprayers where the bypass or prime valve returns fluid back to the container during priming and pressure relief.
The Graco 805077 Bypass Tube is a return line designed for Graco airless paint sprayers. It connects to the sprayer’s bypass or prime valve and allows excess paint or coating material to return to the suction bucket during priming or pressure release. This circulation helps ensure smooth startup, efficient paint flow, and proper pressure control inside the pump system.
When the prime valve is opened, the tube safely redirects paint away from the spray hose and back into the paint container. This process removes air from the pump and prepares the sprayer for consistent spraying performance.
The Graco 805077 Bypass Tube is typically installed in contractor-grade airless paint sprayers where a bypass or prime valve is used. It ensures safe circulation of paint while priming the pump, cleaning the system, or relieving pressure before spraying.
