Pentair filters are known to work well, even when the pool gets a lot of debris. But no matter how good the equipment is, some parts will eventually wear out and need to be replaced. One of the most important components that you must keep an eye on is the Pentair 190003 filter clamp, a heavy-duty metal band that locks the top and bottom halves of your filter tank together and keeps everything sealed under pressure.

This clamp fits several Pentair filter models, so you can use it as a replacement on Clean & Clear Plus, FNS Plus, and Quad D.E. units. By getting the 190003 clamp kit, you benefit from:

• Genuine Pentair construction for dependable performance under high pressure
• Designed tension control to prevent leaks
• Durable materials built for long-term use
• Complete assembly with clamp band, locking hardware, and tension spring

What’s included in the 190003 clamp kit?

• Washer
• Spring cylinder nut assembly

You ...

How to install the Pentair 190003 filter clamp

Pentair designed this clamp with a plug-and-play layout, so you should find it easy and quick to install.

Step 1: Remove the old clamp

Turn off your pump and release pressure from the filter. When the system depressurizes, loosen and remove the existing clamp band.

Step 2: Position the new clamp

Place the Pentair 190003 clamp evenly around the seam where the top and bottom halves of the filter tank meet. Make sure it sits flush all the way around.

Step 3: Tighten the clamp

Secure the tension spring and hardware, then tighten until the clamp feels firm and evenly seated. Don’t overtighten — steady, balanced pressure gives the best seal.

Step 4: Restart and check

Turn your filter back on and inspect the clamp area. Look for leaks and confirm the tank remains tightly sealed during operation.

That’s it — your Pentair filter is ready to run safely again.
