ChangTa Tension Control Clamp Kit for Pentair FNS Plus 190003 — Black-Coated Stainless Steel, Complete Repair Hardware

ChangTa 190003 Tension Control Clamp Kit is a direct-fit stainless steel replacement clamp assembly designed to restore secure, leak-free sealing for Pentair FNS Plus, Clean & Clear Plus, Quad DE and several compatible commercial and residential filter housings.

When a filter clamp fails the result can be leaks, loss of pressure, or even a sudden separation of the tank halves. This ChangTa replacement kit recreates the clamping tension and safety features of the original part using black-coated stainless steel and a complete nut, washer, and spring cylinder assembly. It’s made to match Pentair part fitments including the 190003 group and various Clean & Clear, Quad DE, and Hayward-compatible tanks so you can repair the unit without replacing the entire filter.

How will this clamp kit stop water from leaking around my Pentair filter?

The clamp rebuilds consistent, even tension around the filter lid and body to compress the gasket properly and form a watertight seal. The spring cylinder nut assembly keeps pressure even as the system cycles and as temperature changes occur, reducing the chances of localized gaps that cause drips or sprays.

• Black-coated stainless steel resists corrosion and maintains spring tension.
• Complete tension assembly (clamp, washer, spring nut) replaces worn parts.
• Precision caliper design aligns with OEM groove and bolt placement.
• UV- and weather-resistant finish preserves sealing force outdoors.

Why choose this ChangTa replacement instead of buying a new filter?

Replacing a failed clamp is cost-effective and quick compared with the price and downtime of swapping an entire filter tank. The kit addresses common failure modes—stripped threads, broken clips, and stretched or corroded bands—so the original housing can be safely reused.

• Lower cost than a full filter assembly or tank replacement.
• Fast, plug-and-play installation gets the system back online quickly.
• Meets or exceeds OEM fit and performance for compatible models.
• Includes all hardware, eliminating extra trips for parts.

What models and filters does this clamp kit fit?

This clamp is built to work with Pentair 190003 FNS Plus series (24, 36, 48, 60) and a range of Clean & Clear Plus (CCP240/320/420/520) and Quad DE housings (24–100). It is also compatible with referenced Pentair and Hayward part numbers, but verifying your model number before purchase is recommended.

• Pentair FNS Plus 24, 36, 48, 60 compatibility listed.
• Clean & Clear Plus CCP240/320/420/520 supported.
• Quad DE series and several Pentair/Hayward part cross-references covered.
• Confirm your OEM part number or consult dealer resources first.

How difficult is installation and what tools are needed?

Installation is straightforward for most DIYers: remove the old clamp, position the new band and spring nut assembly, and tighten to the recommended tension. The kit is designed to be plug-and-play with simple hand tools, and many step-by-step videos are available online for visual guidance.

• Typical tools: adjustable wrench or socket set and possibly a screwdriver.
• Installation steps: depressurize filter, remove old band, fit new clamp, tighten evenly.
• Check for leaks under pressure and re-torque if needed after first run.
• Manufacturer-tested parts reduce alignment and fit issues.

Who this is for: pool and spa owners, service technicians, and facilities managers who need a durable, OEM-alike replacement clamp to stop leaks and restore safe operation of Pentair-compatible filters. If you own one of the listed Pentair FNS Plus, Clean & Clear Plus, Quad DE models, or have the referenced part numbers, this ChangTa clamp kit offers a rugged, weather-resistant repair solution without the expense of a full filter replacement.
