Pentair Clamp Ring Kit 190003 for Titan/FNS Filters - Tension-Control Replacement to Restore Seal

Pentair 190003 is a tension-control clamp ring kit designed to replace the clamp assembly on American Products / PacFab Titan and FNS pool and spa filters.

When a filter's clamp becomes worn, cracked, or fails to hold a secure seal, the Pentair 190003 tension control clamp ring kit provides the compatible parts to restore proper compression and reliable operation. This replacement kit matches the original clamp geometry and mounting points used on many Titan and FNS pressure vessels, making it a straightforward swap for maintenance teams, pool professionals, and DIY owners who need to keep filtration tight and leak-free.

How does the Pentair 190003 clamp ring restore my filter's seal?

Replacing the clamp ring renews the clamp's ability to compress the filter joint evenly and maintain the pressure seal between the tank halves. A fresh tension-control clamp eliminates gaps, prevents leaks, and ensures the cartridge or element sits correctly inside the housing.

• Restores original clamp tension for even compression.
• Replaces fatigued or cracked metal to prevent leaks.
• Maintains correct alignment of filter halves under pressure.
• Compatible with Titan and FNS housings for a precise fit.

What parts are included and what tools are needed for installation?

The kit supplies the tension-control clamp ring components required to rebuild the clamp assembly; it typically includes the band, tensioning hardware, and any specific fasteners unique to the 190003 design. Installation is simple with common hand tools and a basic understanding of filter disassembly.

• Includes clamp band and tensioning hardware specific to model 190003.
• Requires basic tools: wrench or socket set, screwdriver, possibly pliers.
• Remove pressure, drain the vessel, and follow manufacturer torque guidance.
• No specialty tools needed for standard Titan/FNS housings.

Which filter models and situations is this clamp ring compatible with?

This Pentair clamp ring is intended for use on American Products / PacFab Titan and FNS-style pool and spa filter vessels that accept the 190003 tension-control clamp kit. It’s the right choice when the existing clamp shows wear, corrosion, or spring/fastener failure.
