The GRACO 563168 is an automatic relief indicator designed for use with MSP, MXP, MHH, and MJ divider valves. It is constructed to allow the lubrication system to continue operating even if a lube point is blocked, by relieving excess pressure and indicating a blockage. The part is typically made from robust materials suitable for industrial environments, though the specific material is not specified in available sources. Its primary function is to maintain system operation and provide visual indication of blockages without requiring manual reset after the blockage is cleared.

Key Features:

• Automatic Relief Indicator
• 563168
• 2500 psi (172 bar)
• MSP, MXP, MHH, and MJ Divider Valves
• Automatic reset after blockage is cleared
• Allows system to continue operating during blockages
