Kit Contents

• 563958 - Blowout Disc (Qty 6 per package)

Package quantity is 6 discs. Part of the rupture-to-atmosphere indicator system that operates by rupturing the pressure disc when predetermined pressure is exceeded, venting lubricant to atmosphere and relieving high pressure. Standard on all GRACO pumps. When pressure reaches predetermined setting, the pressure disc ruptures, venting lubricant into the atmosphere and relieving pressure.
