The OEM Pentair 197020 Clamp Ring is a factory-specified replacement component for Pentair Purex SM 4000 and SMBW 4000 filter systems.

When tightened correctly, this clamp ring eliminates leaks, maintains consistent internal pressure, and ensures your filter system operates at full capacity. It is an essential replacement part for anyone servicing or restoring SM and SMBW 4000 series filtration equipment.
