FILTERUP Tension Control Clamp Kit for Pentair FNS/Clean & Clear — 23-1/4" Stainless Steel, Hand-Tighten

If your pool filter lid is leaking or the clamp hardware is corroded, this FILTERUP kit delivers a direct replacement engineered to fit Pentair FNS Plus, Clean & Clear Plus and Quad DE filter housings. The kit replaces worn tension-control fixtures so you can re-seal the filter bowl quickly without buying a complete assembly. It’s built from corrosion-resistant stainless steel and sized for 23-1/4" filter housings used across a wide range of residential filters.

How will this clamp kit stop leaks on my filter?

The kit restores the mechanical compression that squeezes the O-ring between filter halves. Tightening the new tension knob re-establishes an even, adjustable clamp force so the original gasket seats properly and prevents water seepage.

• 23-1/4" length designed for direct replacement on specified models
• High-strength stainless-steel band resists bending and sustains even pressure
• Knob and hardware allow simple hand-tightening for a secure seal
• Replaces worn or corroded original clamps that cause uneven compression

Which filter models does this FILTERUP kit fit?

The clamp kit is made to be compatible with a long list of Pentair-style filters, including Clean & Clear Plus, FNS Plus and Quad DE families. Check your filter’s part numbers against the compatibility list to confirm fit before ordering.

• Clean & Clear Plus: CCP240, CCP320, CCP420, CCP520 and related part numbers
• FNS Plus: FNS 24/36/48/60 and matching Pentair part numbers
• Quad DE/Fullfloxf series and other listed models in the product fitment
• Follow the provided part-number list if unsure about interchangeability

How easy is installation and what tools do I need?

Installation is straightforward and intended for DIYers comfortable with basic pool maintenance. The process involves removing the old clamp, fitting the new components, tightening the band, and testing under pressure.

• Simple four-step process: remove old clamp, assemble accessories, tighten clamp, test operation
• Hand-tightenable knob eliminates the need for special tools in most cases
• Inspect the filter O-ring during installation and replace if cracked or flattened
• Allow for a pressure test cycle to confirm there are no leaks after installation

What is the material quality and how long should it last?

The band and hardware are manufactured from stainless steel formulated to resist rust and maintain strength under normal pool conditions. Proper installation and routine pool chemical balance will maximize longevity.

• Stainless-steel construction for corrosion resistance and mechanical integrity
• Designed to hold compression under typical pump pressures without deforming
• Seals and knobs are rated for regular pool service; replace O-ring if worn
• FILTERUP offers a 12-month after-sales support window for customer questions
