Durable design for real world use

The cartridge features corrosion resistant end caps that hold up against chemical exposure, helping to prevent melting or breakdown. The pleated media is reinforced with a robust banding to resist warping and maintain shape even during backwashing, so it stays reliable over time.

• Corrosion resistant end caps
• Sturdy pleated fibers reinforced with banding
