This is a stuffing box nut, a specialized fastener used on petroleum tank trailers to compress packing material around a valve stem or pump shaft.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It creates a tight seal that prevents liquid or vapor leaks during loading, unloading, or transport. Replacing a worn or corroded stuffing nut is necessary when you see persistent weeping from the shaft seal that can't be stopped by tightening. Keeping this hardware in good shape helps maintain product integrity and safety when hauling fuels and chemicals.
