Pentair 190003 Spring Clamp Band Kit for FNS Plus, Quad DE & Clean & Clear Plus

Pentair 190003 Spring Clamp Band Kit for FNS Plus, Quad DE & Clean & Clear Plus

Replace a stretched, corroded or damaged tank clamp on a Pentair cartridge or D.E. filter with the genuine Pentair 190003 spring clamp band kit. The spring-style clamp band seals the filter tank halves together, and its spring tension assembly keeps clamp load even as the tank cycles under pressure.

🚩 PRO TIP: This spring-style 190003 clamp fits filters manufactured before September 2025; filters built after the clamp design change use a different cast clamp and the two are not interchangeable — check your filter's manufacture date before ordering. Tighten the barrel nut until the spring coils touch, working to the torque sequence in your filter manual.

FREQUENTLY ASKED QUESTIONS:

• Which filters does the Pentair 190003 clamp band kit fit? The Pentair 190003 fits Pentair Clean & Clear Plus CCP240 through CCP520 cartridge filters, FNS Plus 24 through 60 sq ft D.E. filters, Quad D.E. 60, 80 and 100 filters, and FullFloXF F-Series and C-Series filters.
• Will the Pentair 190003 fit a filter made in late 2025 or 2026? No — the Pentair 190003 is the spring-style clamp for filters manufactured before September 2025. Filters built after the design change use a cast clamp assembly and the two clamps are not interchangeable.
• My filter drips at the tank seam — is the clamp the problem? A seam drip on an FNS Plus, Quad D.E. or Clean & Clear Plus filter is often a stretched or unevenly tensioned clamp band or a worn tank O-ring; the Pentair 190003 replaces the spring clamp band so the tank halves seal evenly again.
