The GRACO 551390 is a sightglass beaker, typically made of clear, durable material (likely glass or robust plastic), designed for measuring and monitoring fluids within GRACO equipment. Its primary function is to provide a visible, graduated container for fluid level observation and measurement in industrial lubrication or spray systems.

Key Features:

• Sightglass beaker
• 1000 ml, graduated
• Compatible with GRACO equipment requiring a sightglass beaker for fluid monitoring
• Graduated markings for accurate measurement
• Transparent for easy visual inspection
• Designed for reliability and ease of maintenance

Applications:
Used in industrial lubrication, spray, and maintenance systems for monitoring and measuring fluid levels in GRACO equipment.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of your equipment.
• Ensure the beaker is securely fitted to prevent leaks
• Regularly inspect for cracks or cloudiness that may impair visibility
• Clean periodically to maintain clear sight of fluid levels
