GRACO 564355 - Trabon Replacement Rupture Indicator, 1/8-27 NPT(F), 4600 PSI
Trabon rupture indicator designed for MH divider valve applications where lube system pressures exceed 2,500 PSI. When high pressure from lube line blockage causes the disc to rupture, lubricant forces an indicator pin to protrude, locating the blockage. The high pressure then backs up through the system and trips a switch to shut the system off, providing automatic system protection and fault detection.
Trabon Performance Indicators are pressure-sensitive devices that pinpoint excessive pressure in Trabon series progressive lubricating systems. These devices, which are installed in the alternate outlet ports of divider valves, signal a fault either by causing an indicator pin to protrude or by releasing lubricant to the atmosphere. All Performance Indicators respond quickly to protect the lube system and locate lube line blockage.
Used on MH divider valve applications where lube system pressures exceed 2,500 PSI (172 bar).
- High pressure from blockage causes a disc to rupture.
- Lubricant forces an indicator pin to protrude, indicating the blockage.
- High pressure backs up through the system and trips a switch to shut the system off.
- When fault is corrected, disc must be replaced and pin reset.
- Divider Valve Rupture Indicators w/Memory - 4,600 PSI

Part of the MS, MH and MXP Rupture Indicators with Memory family. Also has replacement disc options available in various colors (557423-Yellow, 557424-Red, 557425-Orange, 557427-Pink) Part of the Trabon Performance Indicators product line. Disc must be replaced and pin reset manually after fault correction. Replacement disc part number 557424 available separately. Used only on MH divider valve applications where lube system pressures exceed 2500 PSI. High pressure from lube line blockage causes a disc to rupture, forcing an indicator pin to extend showing the blockage. When fault is corrected, the disc must be replaced and the pin reset manually.
