The GRACO 189988 GUIDE, PISTON, SST is a precision-engineered guide component designed to support and align the piston within GRACO displacement pumps. Its material is not explicitly specified in available documentation, but it is typically constructed from durable metals or alloys for longevity and reliability. This part is essential for ensuring smooth piston movement and proper sealing within GRACO pump assemblies, contributing to efficient fluid transfer and system integrity.

Key Features:

• Guide, Piston
• Compatible with GRACO displacement pumps (e.g., Check-Mate Lowers, Check-Mate 2100 Pumps)
• Supports and aligns piston for smooth operation
• Contributes to reliable sealing and pump efficiency
• Designed for durability in industrial environments

Applications:
Used in GRACO displacement pumps for lubrication, fluid transfer, and maintenance applications across industries such as mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and compatibility with GRACO equipment, reducing the risk of premature wear or system failure.
• Lubricate all soft seal components before installation as recommended by GRACO manuals
• Follow torque specifications and assembly procedures outlined in the equipment manual
• Inspect for wear or damage before installation and replace if necessary
