Installation & Maintenance Notes
Use this kit whenever the original clamp band on your filter tank becomes worn, damaged, or is no longer providing a tight seal. Before re-clamping, inspect (and if needed replace) the filter tank O-ring, clean the sealing surfaces, then evenly seat the clamp band around the tank and tighten the barrel nut to Pentair’s torque specification to ensure a pressure-tight seal. Avoid overtightening — just enough to compress the O-ring uniformly. Routine inspection of the clamp and O-ring during seasonal maintenance helps prevent leaks and prolong filter life.
