Rupture Indicators

Graco rupture indicators from MotionSource keep your machine running while lubrication gets to critical points. Graco rupture indicators pinpoint lube line blockages forcing an indicator pin to protrude, indicating the blockage.

Rupture Indicators

Rupture indicators give the freedom of no time or effort required searching for the blockage and allows your machine to continue to run while non-critical bearings are lubricated. For use with MHH divider valves, rupture indicators provide easy information on blocked lines, high system pressure or blocked bearings.

Graco indicators are the same Trabon Indicators you have relied on for decades. They 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.
