Kit Contents

• 25 red blowout discs rated for 1750 PSI

Part of the rupture-to-atmosphere indicator system. Discs up to 2,350 psi have a tolerance of ± 500 psi. Discs greater than 2,350 psi have a 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). This is part of the blowout disc family with different pressure ratings and colors.
