The GRACO 563223 is a rupture indicator designed for use in Trabon series progressive lubrication systems. It is constructed for compatibility with oil and is intended to detect and signal excessive pressure within in-plant machinery and compressor equipment, helping to protect the system from damage due to overpressure.

Key Features:

• Rupture Indicator (Relief Indicator)
• Trabon, 1/8-27 NPTF
• Maximum working pressure: 5500 psi (379 bar, 38 MPa, 37900 kPa)
• Oil
• Pressure-sensitive device for pinpointing excessive pressure
• Quick response to protect lube system and locate blockages
• Indicator pin protrudes or releases lubricant to atmosphere upon fault
• Stops lube system operation when a fault occurs
• Reliable and easy to maintain

Applications:
In-plant machinery, compressor equipment, and other applications where progressive lubrication systems require protection from overpressure and need to quickly locate blockages.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Install in indicator ports (alternate outlets) of divider valves as specified in the system manual
• Ensure proper thread engagement for 1/8-27 NPTF connection
• After a fault, replace the disc and reset the indicator pin manually
• Regularly inspect for signs of pressure faults or leaks
