This is a replacement disc for a 5-inch air valve, commonly used on dry bulk pneumatic trailers.
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.
The disc is the internal moving component that opens or closes to control the flow of air or dry bulk material (like cement, sand, or plastic pellets) through the system. Over time, the original disc can wear out, crack, or fail to seal properly, leading to air leaks and inefficient unloading. Replacing it with this disc restores a tight shutoff and keeps your trailer's pneumatic system operating reliably.
