GRACO 563964 – Blowout Disc Kit – (6) Orange, 2050 PSI, 11/16″, 1/8 NPTF

Orange 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 the system.
