GRACO 563176 - Valve Relief Indicator O-Ring 3000 PSI, 1/8" Npsf w/o-Ring

Automatic Relief Indicator that pinpoints lube line blockage while allowing the lube system to continue supplying lubrication to points that are not blocked. Used primarily in secondary divider valves, this indicator detects excessive pressure created by line blockage and moves a piston to enable lubricant escape through a vent. When blockage is restored, the spring resets the piston, allowing the lube system to keep operating even when a lube point is blocked.
