    • 6 x Yellow rupture discs rated for 1,450 PSI

    Part of rupture-to-atmosphere indicator system. Discs up to 2,350 PSI have a tolerance of ±500 PSI, while discs greater than 2,350 PSI have a tolerance of ±20%. This is a replacement disc package - complete assemblies and individual replacement discs are also available. Standard on all GRACO pumps. When pressure reaches predetermined setting, pressure disc ruptures, venting lubricant into atmosphere and relieving pressure. All pressures have tolerance of +500 PSI (3.4 MPa, 34.5 bar) All rupture discs have 11/16 in. diameter. This appears to be a 6-pack quantity based on the pattern with other similar part numbers in the table.
