Got a Permco 5000 series pump that's been weeping fluid at the mating surfaces for a while now. This the right seal to fix that?

Answer by: Customer Support on Sep 11, 2025, 7:05 PM

For leakage between mating surfaces on a 5000 series unit, yes, that's exactly what this seal addresses. It's a direct-fit replacement sourced from Permco, so it's built to the same specs as what came in the unit originally. If you're cross-referencing, it also goes by part number C1DD70, which can help if you're pulling an old parts list.
