Pentair 197020 Clamp Ring Assembly

This specific clamp assembly is designed exclusively for the Pentair SM and SMBW 4000 Series pool and spa filters. Before purchasing, verify your filter model number on the tank label to ensure compatibility, as this part is not universal.

You should replace the clamp ring if you notice visible cracks, significant corrosion, or if the threads are stripped and no longer tighten properly. If your filter tank is leaking at the seam despite tightening the clamp, the ring may have lost its structural integrity and needs a replacement.

Yes, the 197020 assembly includes the essential hardware required to secure your filter tank halves. It is designed as a direct replacement, so you should be able to swap out your old, worn-out clamp with this new unit using standard tools.

Installing the clamp ring is a straightforward maintenance task, but it requires care to ensure the tank halves are perfectly aligned before tightening. Always turn off your pool pump and relieve all pressure from the filter system before attempting any installation to ensure your safety.

A new clamp ring often resolves leaks caused by a loose or damaged connection, but it is not a guaranteed fix if the tank gasket or O-ring is also worn out. We recommend inspecting your tank O-ring while the clamp is off and replacing it simultaneously to ensure a complete, leak-free seal.
