Piston Shaft Seal

Part #: 

This U-cup seal is for the shaft that connects to the handle on a drywall loading pump. If you pump is leaking mud out the top where the shaft goes through thr brass nut, It's very like that this seal needs replaced. Make sure when you install it to clean the crud out from underneath the brass nut, and face the cup of this seal down, not up.
