Parker S23R20A String-wound Filter 5 Micron 20in Polyester

Product Description

The PARKER S23R20A is a string-wound cartridge filter designed for plumbing and water filtration applications requiring reliable particulate removal. Built from FDA-grade polyester with a polypropylene plastic core, this filter measures 2.5 inches in outside diameter and 20 inches in length, providing a substantial filtration area. The 5 micron rating captures fine sediment, sand, rust, and other suspended solids from potable and process water lines. It is rated for use at temperatures up to 120 degrees F, making it suitable for cold and cool water service. Plumbers and water treatment technicians install this filter in standard 20-inch big-blue or slim-line filter housings.

The S23R20A is well suited for residential and light commercial water treatment systems where consistent sediment reduction is required ahead of softeners, RO membranes, or point-of-use fixtures. String-wound construction provides graduated density filtration, capturing larger particles at the outer layers and progressively finer particles toward the core, which extends service life and helps maintain flow rates. Common installation scenarios include well water prefiltration, irrigation line protection, and commercial food-service water prep lines where FDA-grade materials are required.

Installation Notes

Installation should be performed by a licensed plumber or qualified water treatment technician. Shut off the supply valve and relieve system pressure completely before opening the filter housing. Inspect the housing O-ring for wear or damage and replace it if needed before seating the new cartridge. Follow local plumbing codes and the housing manufacturer guidelines for torque and reassembly procedures.
