The GRACO 258769 KIT,HYD PISTON ASSEMBLY is a replacement hydraulic piston assembly designed for use in GRACO hydraulic equipment. It includes a hydraulic piston rod and a bidirectional piston seal. The assembly is intended to restore or maintain the hydraulic actuation function within GRACO proportioning pumps and related systems, ensuring reliable operation in demanding industrial environments. Material specifics are not detailed, but typical GRACO hydraulic assemblies use high-grade steel and engineered polymers for seals.

Key Features:

• Hydraulic piston assembly kit
• High-grade steel (rod), engineered polymer (seals)
• Designed for GRACO hydraulic equipment, especially proportioning pumps and hydraulic actuators
• Includes hydraulic piston rod and bidirectional piston seal
• Engineered for reliability and durability in industrial applications
• Supports high duty cycles and demanding environments
• Ease of maintenance with replaceable components

Applications:
Used in GRACO hydraulic proportioning pumps and actuators for fluid transfer and metering in industrial, mining, and agricultural settings. Suitable for professional use only and not for explosive atmospheres.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of hydraulic systems. Non-genuine parts may compromise safety and equipment longevity.
• Always follow GRACO equipment manuals for installation procedures
• Ensure hydraulic system is depressurized before installation
• Inspect all seals and rods for damage prior to installation
• Use appropriate tools and safety equipment
• Verify compatibility with your specific GRACO equipment model
• Regularly inspect hydraulic assemblies for wear and leaks
• Replace seals and rods as part of scheduled maintenance
• Keep hydraulic fluid clean and at recommended levels
• Follow GRACO’s maintenance guidelines for optimal performance
