The GRACO 15G852 is a displacement rod designed for use in GRACO equipment, specifically as a replacement or maintenance part for pumps and related machinery. The material is not specified in available sources, but it is intended to function as a critical internal component that facilitates the movement and operation of the pump mechanism. Its primary use is to ensure proper displacement and smooth operation within compatible GRACO pump assemblies.

Key Features:

• Displacement rod
• 18 cm (length not fully specified; product listings mention 18 cm displacement, but physical length may differ—see below)
• For use with GRACO pump assemblies, specifically referenced for use with part 249992 (as per some listings)
• Precision-engineered for reliable operation
• Designed for easy replacement and maintenance
• Critical for pump displacement function

Applications:
Used in GRACO pump assemblies for industrial, mining, agricultural, and maintenance applications where reliable fluid transfer and displacement are required.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the equipment.
• Always use a rubber mallet or arbor press to drive the displacement rod into the cylinder; never use a hammer to avoid damage.
• Place the cylinder on a soft block of wood during installation to protect the rod and cylinder.
• Lubricate o-rings and fittings as specified in the manual before installation.
• Follow torque specifications for fittings (e.g., 156–171 N•m or 115–126 ft-lb for certain assemblies).
