GRACO 563221 - Trabon Rupture Indicator, 1/8"-27 Npsf w/o-Ring, 255 Bar (3700 PSI)

Trabon rupture indicator designed for MH divider valve applications where lube system pressures exceed 2,500 psi. Features high pressure protection by causing a disc to rupture when lube line blockage occurs, forcing an indicator pin to protrude and locating the blockage while backing up through the system to trip a switch and shut the system off.

Part of the MS, MH and MXP Rupture Indicators with Memory and O-Ring Seal family. Replacement discs available in yellow for this pressure rating. When fault is corrected, the rupture disc must be replaced and the pin reset manually. Part of Trabon Performance Indicators product line. Rupture Indicators are only used on MH divider valve applications where lube system pressures exceed 2500 psi. High pressure from the lube line blockage causes a disc to rupture. The lubricant then forces an indicator pin to extend, showing the blockage. When the fault is corrected, the disc must be replaced and the pin reset manually.
