Technical Specifications

Function & Role in the System

The suction tube forms the essential link between the material container and the pump. It helps maintain a steady flow by ensuring the pump has constant access to fluid, and the built-in strainer prevents large particles or debris from entering the pump, protecting the internal components.

Applications & Compatibility

The 15D157 tube is listed in Graco’s parts documentation for its 5-gallon suction set kits. In particular:

• Used in Graco 5-gallon suction systems in stand sprayers. 
• Part of Graco suction assemblies that include the strainer, hose, and clamp for fluid pick-up from a pail.
• Included in Graco LoBoy stand suction set kits. 

Installation & Maintenance

• Before installing, make sure the container and the fluid are clean to avoid drawing in contaminants.
• Secure the strainer screen in place and clamp the tube tightly to prevent vacuum leaks.
• Inspect the strainer periodically for clogging and clean or replace if blocked.
• Replace the tube if it shows signs of cracking, brittleness, or wear to avoid air ingestion into the pump.
• During reassembly, ensure the hose clamp is correctly tightened but not over‑torqued, to avoid damaging the tube.
