GRACO 563225 - Trabon Replacement Rupture Indicator, 1/8-27 NPT(F), 6400 PSI

Trabon rupture indicator designed for MH divider valve applications where lube system pressures exceed 2,500 PSI. Features a disc that ruptures under high pressure from lube line blockage, forcing an indicator pin to protrude and locate the blockage while backing up through the system to trip a switch and shut the system off. Essential safety component for high-pressure lubrication systems.

Part of the rupture indicators with memory series, with replacement disc available (557427) When fault is corrected, the disc must be replaced and the pin reset manually. Part of the Trabon Performance Indicators product line. High pressure from lube line blockage causes a disc to rupture. The lubricant then forces an indicator pin to extend, showing the blockage. The high pressure backs up through the system and trips a switch that turns the system off. When the fault is corrected, the disc must be replaced and the pin reset manually. Used only on MH divider valve applications where lube system pressures exceed 2500 PSI (17 MPa, 172 bar).
