A secure filter clamp is critical to safe pool operation. The Swimables Filter Clamp Nut (SW-26-997) is a direct replacement designed to properly secure the clamp band on Pentair® FNS Plus, Quad DE, and FullFloXF pool filters, ensuring even pressure distribution and a reliable tank seal.

Over time, original clamp nuts can strip, crack, or corrode due to repeated service, chemical exposure, or overtightening. When the clamp nut fails, the filter may not seal correctly—leading to leaks, pressure loss, or unsafe operating conditions. This replacement clamp nut restores proper clamping force so your filter operates exactly as intended.

Manufactured for durability and precise fit, the SW-26-997 is ideal for routine maintenance, filter rebuilds, or safety-related repairs.
