GRACO 563954 - Blowout Disc Kit - (25) Yellow, 1450 PSI, 3/8", 3/8" NPTF

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

Kit Contents

• 25 yellow blowout discs rated for 1450 PSI

Part of the rupture-to-atmosphere indicator system. Disc must be replaced after activation and pin reset manually when fault is corrected. Standard blowout disc for Rupture-to-Atmosphere Indicators on 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).
