Because it is supplied without the O-ring, it works well for buyers who are sourcing the seal separately or already have a serviceable gasket on hand.The 634000 is a practical replacement when a compatible Waterco SupaTuf or HydroStorm pump needs a fresh 6-3/4 inch trap lid to restore cleaner closure and easier maintenance access.
