Dayton PPTPXX303G Seal 303
The Dayton PPTPXX303G is a replacement seal built for straight centrifugal pumps carrying the Dayton name. It fits the Grainger 5PXX3 and Dayton 5PXX3 model numbers directly. Maintenance teams and plant engineers use it to restore sealing integrity on compatible pump assemblies.
Seal compatibility limits
The seal works only with straight centrifugal pumps from Dayton that match the 5PXX3 part reference. It will not fit other pump types, other brands or Dayton models outside that reference. The carbon and ceramic gasket materials set the chemical and temperature boundaries for the fluid being pumped.
Replaces worn original seal
This part replaces the factory seal when leakage or wear appears on a Dayton 5PXX3 pump. The upgrade is justified when the existing seal no longer holds pressure or shows scoring on the carbon or ceramic faces. It is not for pumps of a different design or for converting a pump to a new sealing arrangement.
