Why Clamp Nuts Are Essential
Clamp systems keep your filter tank halves tightly secured. Without strong, properly functioning nuts, your filter system can face:
-
Leaks around the tank seam
-
Loss of system pressure and reduced filtration efficiency
-
Risk of tank separation under pressure
-
Added stress on pumps and plumbing
Replacing damaged clamp nuts with Swimables SW-26-997 ensures your filter remains safe, sealed, and operating at peak performance.
Signs It’s Time to Replace Your Clamp Nut
Over time, clamp nuts wear out from constant tightening, chemical exposure, and UV damage. It may be time for a replacement if you notice:
-
Cracks, splits, or stripped threads in the nut
-
Leaks appearing at the tank seam
-
Difficulty tightening the clamp during maintenance
-
Loose or unstable clamp connection
-
A missing nut from your assembly
By swapping in the Swimables replacement nut, you prevent small problems from turning into major equipment failures.
