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

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).
