GRACO 563226 - Trabon Replacement Rupture Indicator, 1/8-27 NPSF w/ O-Ring, 6400 PSI

Trabon replacement rupture indicator designed for MH divider valve applications where lube system pressures exceed 2,500 psi. Features high pressure disc that ruptures during lube line blockage, forcing indicator pin to protrude and locate the blockage while backing up through system to trip switch and shut system off. Includes O-ring seal for reliable performance.

Part of the MS, MH and MXP Rupture Indicators with Memory and O-Ring Seal family. Replacement discs available separately. When fault is corrected, the disc must be replaced and pin reset manually. Part of the Trabon Performance Indicators product line. Rupture Indicator for MH Divider Valves Only. Used on MH divider valve applications where lube system pressures exceed 2500 psi (17 MPa, 172 bar). High pressure from the 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.
