GRACO 563959 - Blowout Disc Kit - (25) Blue, 2950 PSI, 3/8", 3/8" NPTF

Blue blowout disc package for rupture-to-atmosphere indicators that provide pump protection and visual indication of excessive system pressure. When system pressure exceeds the preset level, the pressure disc ruptures at a predetermined pressure setting, venting lubricant to atmosphere and relieving high pressure to protect equipment.
