GRACO 563956 - Blowout Disc Kit - (25) Orange, 2050 PSI, 3/8", 3/8" Diameter

Blowout disc package for rupture-to-atmosphere indicators that provide pump protection and visual indication of excessive system pressure. The pressure disc ruptures at a predetermined pressure setting, venting lubricant to the atmosphere and relieving high pressure in MH divider valve applications.

Kit Contents

• 25 Orange blowout discs rated for 2,050 PSI

Part of rupture-to-atmosphere indicator system. Discs greater than 2,350 psi have a tolerance of ± 20%. Used in conjunction with complete assembly and replacement disc components. Standard on all GRACO pumps. When pressure reaches predetermined setting, the pressure disc ruptures, venting lubricant into the atmosphere and relieving pressure. All pressures have a tolerance of ± 500 psi (3.4 MPa, 34.5 bar)
