The TRP Loose Wheel Nut Indicator (Dustite) Part No. 9506919 is an essential visual safety aid for all commercial vehicle wheels. Designed to fit over the wheel nuts, this indicator provides maintenance personnel and drivers with an immediate visual check of the wheel nut torque status.

The device serves two critical functions:

Visual Safety Check: The high-visibility indicator is placed with its pointer aligned with the others. If a wheel nut begins to loosen, the indicator will rotate out of alignment, providing an instant, clear warning that maintenance is required before a serious failure occurs.

Nut Protection: The ‘Dustite’ design features an integrated cap that seals the wheel nut against external elements, protecting it from moisture, dirt, and road grime. This corrosion protection helps maintain the integrity of the nut and simplifies future removal.

The TRP 9506919 is a simple, cost-effective way to enhance road safety and reduce the risk of catastrophic wheel loss in heavy-duty transport.
