Caterpillar Compactor Overhaul Gasket Set – HCB164-8900

Made of very strong material and is very long-lasting.
Condensation and wet grain or corn will not corrode poly lining when the metal is covered with poly. 
When the metal lining is corroded, the poly lining keeps loose grain from falling through rust holes and feeds grain evenly into the throat of the combine.
Decrease risk of trough breakage during the harvest.
Save money in the long run.
