Product Overview

The Graco 15F659 Outlet Housing 85/115 is an OEM outlet‑housing assembly designed for use with Graco 85 cc and 115 cc pump lowers that incorporate a built‑in filter system. It serves as the fluid outlet port housing, providing the connection point through which pumped material exits toward the fluid line or spray hose. This housing is machined to factory tolerances, ensuring proper alignment, reliable sealing, and structural integrity under pressure — essential for efficient, leak-free operation of industrial spray systems.

Installation / Replacement Instructions

Follow these steps to safely replace the 15F659 outlet housing:

• Ensure the pump is depressurized and fluid drained before disassembly.
• Remove the old outlet housing carefully — loosen housing bolts/nuts and lift housing straight off the lower cylinder to avoid damaging the displacement rod.
• Clean all mating surfaces and fluid passages thoroughly — remove old gaskets, O‑rings or debris.
• Install the new 15F659 housing — align bolt holes and sealing surfaces correctly; tighten bolts to manufacturer‑specified torque. After reassembly, test with low pressure fluid or solvent to confirm no leaks before normal operation.
