The GRACO 563221 is a pressure-sensitive rupture indicator designed for use in Trabon® progressive lubrication systems. It is constructed to be compatible with oil and is intended to detect and indicate excessive pressure caused by line blockage, allowing the system to continue supplying lubrication to unaffected points. The indicator features an O-ring for improved sealing.

Key Features:

• Rupture Indicator
• 1/8-27 NPSF
• Maximum working pressure: 3700 psi (255 bar, 25500 kPa)
• Oil
• Pressure-sensitive device for detecting excessive pressure
• O-ring included for improved sealing
• Designed for use in Trabon® progressive divider systems
• Allows lubrication system to continue operation during line blockage

Applications:
Used in Trabon® progressive lubrication systems for in-plant machinery and compressor equipment to monitor and indicate excessive pressure due to line blockage.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance within the lubrication system.
• Ensure proper thread engagement (1/8-27 NPSF)
• Check O-ring for integrity before installation
• Install in accordance with system pressure requirements
• Regularly inspect for signs of rupture or excessive pressure
• Replace indicator if rupture or excessive pressure is detected
• Follow manufacturer guidelines for maintenance and replacement intervals
