The GRACO 563172 is an automatic relief indicator designed for use with MSP, MXP, MHH, and MJ divider valves. It features an O-ring seal and is constructed for reliable operation in lubrication systems. Its primary function is to indicate when pressure relief occurs due to blockages, allowing lubricant to vent to atmosphere and helping to protect the system from overpressure. Material is not explicitly specified in available documentation, but similar indicators are typically made from carbon steel or stainless steel.

Key Features:

• Automatic Relief Indicator
• 1/8 in. NPT
• 1250 psi (17 bar)
• MSP, MXP, MHH, and MJ Divider Valves
• Spring-loaded piston unseats when blockage occurs, venting lubricant to atmosphere
• O-ring seal for reliable sealing
• Pressure rating stamped on the body for easy identification
• Designed for easy maintenance and reliable operation in demanding environments
• Helps maintain system operation even when a lube point is blocked

Applications:
Used in lubrication systems to indicate and relieve pressure when blockages occur, protecting equipment from overpressure and ensuring continuous operation.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure correct thread size (1/8 in. NPT) and pressure rating (1250 psi) for your application
• Inspect O-ring for damage before installation
• Tighten securely to prevent leaks
• Regularly check the indicator for signs of relief or wear
• For best results, follow manufacturer’s installation and maintenance guidelines
