Parker N15R20A Cartridge Filter 20 Micron Nylon 20 in

Product Description

The PARKER N15R20A is a string-wound plumbing cartridge filter designed for sediment removal in water filtration applications. With a 20-micron rating, it captures fine particulate from supply lines, protecting downstream fixtures, valves, and equipment. The filter body is constructed from nylon with a polypropylene plastic core, offering durability in standard residential and light commercial water systems. At 20 inches long and 2.5 inches in outside diameter, it fits standard filter housings commonly found in whole-house and point-of-entry setups. Rated to a maximum working temperature of 120 degrees F, it is suited for cold and cool water service. Plumbers and water treatment technicians are the primary installers.

This cartridge filter is used in residential and light commercial plumbing systems where sediment, rust, sand, and fine particulate must be removed from the water supply. Typical installations include whole-house pre-filtration, irrigation system protection, and point-of-entry filter housings. The 20-micron rating makes it appropriate for applications where moderate sediment loads are present and protection of downstream fixtures or equipment is required. Its string-wound construction provides depth filtration, trapping particles throughout the filter media rather than only at the surface.

Installation Notes

Installation should be performed by a licensed plumber or qualified water treatment technician.

Inspect the housing o-ring for wear or damage during each cartridge change and replace as needed to prevent leaks. Follow all applicable local plumbing codes when installing or servicing filtration equipment.
