The GRACO 15K888 is a piston support ring designed to secure and stabilize pistons within GRACO pump assemblies. It is typically used in conjunction with pistons and metering tubes for precise material dispensing. The specific material is not specified in available documentation, but GRACO piston support rings are commonly made from durable plastics or engineered polymers for wear resistance and compatibility with various fluids. Its primary function is to maintain piston alignment and support within the pump assembly, ensuring reliable operation and longevity of the equipment.

Key Features:

• Piston Support Ring
• For piston sizes 320-629cc (as referenced in GRACO documentation for similar parts)
• Compatible with GRACO piston assemblies for 320-629cc piston sizes (as referenced in GRACO parts lists)
• Supports and stabilizes piston within pump assembly
• Designed for durability and wear resistance
• Facilitates easy maintenance and replacement

Applications:
Used in GRACO pump assemblies for accurate metering and dispensing of liquids in industrial, agricultural, and maintenance applications. Suitable for use in equipment requiring reliable piston support and alignment.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, function, and longevity of the equipment. Non-genuine parts may compromise performance and safety.
• Ensure the pump is depressurized and isolated from power before installation.
• Follow the equipment manual for specific installation procedures.
• Inspect the support ring and piston for wear or damage before installation.
• Lubricate o-rings and mating surfaces as recommended by GRACO.
• Tighten all fasteners to the specified torque.
• Regularly inspect the piston support ring for signs of wear or damage.
• Replace the support ring during routine maintenance or if excessive wear is detected.
• Keep spare parts on hand to minimize downtime.
