GRACO 563960 - Blowout Disc Kit - (25) Purple, 3250 PSI, 3/8", 3/8 in Diameter

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

Kit Contents

• 25 purple blowout discs rated for 3250 PSI

Part of Trabon Performance Indicators product line. Used as replacement discs in rupture-to-atmosphere indicators. Purple color indicates 3250 PSI pressure rating. Standard on all GRACO pumps. When pressure reaches predetermined setting, the pressure disc ruptures, venting lubricant into atmosphere and relieving pressure. All pressures have a tolerance of +/- 500 PSI (3.4 MPa, 34.5 bar).
