The Pentair 181010 FNS Clamp Spring Kit Replacement is an OEM replacement clamp spring kit used on select Pentair FNS D.E. pool and spa filter clamp assemblies.

Compatibility Notes

The Pentair 181010 clamp spring kit is intended for use with compatible Pentair FNS filter clamp assemblies. Before ordering, always confirm your filter model number and replacement part diagram to make sure 181010 is the correct spring kit for your specific filter.

Important: Filter clamp hardware is a safety-critical part of the pressure vessel. Do not substitute non-OEM bolts, springs, nuts, or hardware. If your clamp band itself is bent, cracked, badly corroded, or no longer seats correctly, the complete clamp assembly may need to be inspected or replaced.

ATB Fitment Tip

If you are unsure whether Pentair 181010 fits your filter, check the model label on the filter tank and compare it to your Pentair parts breakdown before installing. Matching the correct clamp hardware is essential for safe operation.

When Should This Part Be Replaced?

  • The clamp spring is stretched, rusted, or damaged
  • The clamp no longer tightens evenly
  • The filter clamp hardware is difficult to thread or tension properly
  • The filter has been serviced multiple times and the spring hardware is worn
  • You are rebuilding or servicing a compatible Pentair FNS filter clamp assembly
