GRACO 563961 - Blowout Disc Kit - (25) Brown, 5000 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. When pressure exceeds the predetermined setting, the disc ruptures to vent lubricant to atmosphere and relieve high pressure, protecting your lubrication system from damage.

Kit Contents

• 25 brown blowout discs rated for 5000 PSI

Part of the rupture-to-atmosphere indicator system. Discs up to 2350 PSI have tolerance of ± 500 PSI, discs greater than 2350 PSI have tolerance of ± 20%. Standard on all 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).
