GRACO 563174 - Valve Relief Indicator O-Ring 2000 PSI

2,000 PSI relief indicator component designed for use in GRACO G3 Pro Grease and MSP Series Progressive triplex pumping systems. This indicator provides visual confirmation of system relief valve activation, helping operators monitor system pressure and maintain optimal performance in automated lubrication applications.

Keep your machine running while lubrication gets to critical points. These performance indicators pinpoint lube line blockages but allow the lube system to continue to supply lubrication to points that are not blocked.
