Parker N23R20A Cartridge Filter 5 Micron 20 Inch Nylon

Product Description

The PARKER N23R20A is a string-wound cartridge filter designed for plumbing and water filtration applications. It measures 20 inches in length with a 2.5 inch outside diameter and delivers 5 micron filtration to remove sediment, dirt, rust, and particulate matter from water lines. The nylon construction with a polypropylene plastic core provides durable performance in standard residential and light commercial water systems. Licensed plumbers and water treatment technicians install this filter in housings sized for 20-inch cartridges as part of whole-house or point-of-entry filtration setups. It is rated for water temperatures up to 120 degrees F.

This filter is suited for residential and light commercial plumbing systems where sediment reduction is required ahead of downstream fixtures, water heaters, or appliances. String-wound construction provides graduated density filtration, trapping larger particles in the outer layers and finer particles toward the core. It is installed in standard 20-inch big-blue or equivalent filter housings and is a common replacement element in whole-house prefiltration systems and irrigation supply lines requiring particulate control.
