The GRACO 255538 KIT, PISTON, L500 (ALL) is a replacement piston kit designed for use in GRACO L500 series pumps. The kit is intended to restore or maintain the performance of the pump by providing a new piston assembly. The specific material is not specified in available documentation, but GRACO piston kits for L500 models are typically constructed from high-grade, wear-resistant materials suitable for industrial lubrication and fluid handling applications.

Key Features:

• Piston Kit
• L500 (ALL)
• GRACO L500 series pumps
• Designed for easy replacement and maintenance
• Supports reliable pump operation
• Engineered for heavy-duty and continuous use

Applications:
This piston kit is used in industrial lubrication and fluid transfer systems, particularly in environments requiring robust and reliable pump performance, such as mining, agriculture, and manufacturing.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, longevity, and safety of the equipment. Non-genuine parts may compromise pump reliability and void warranties.
• Refer to the GRACO L500 series pump manual for detailed installation instructions
• Ensure all components are clean and free of debris before installation
• Use appropriate tools and follow torque specifications for assembly (for L500 models, piston guide torque is typically 95–115 ft-lbs (128–155 N•m) for severe duty applications)
• Lubricate seals and moving parts as recommended in the manual
