Parker T15R20A String-wound Cartridge Filter 20 Micron

Product Description

The PARKER T15R20A is a string-wound polypropylene cotton cartridge filter designed for plumbing and water filtration applications. Measuring 20 inches in length with a 2.5-inch outside diameter, this filter delivers 20-micron particulate removal to protect downstream equipment and maintain flow quality. The string-wound construction provides graduated density filtration, capturing larger particles at the outer layers and progressively finer particles toward the core. A polypropylene plastic core provides structural support throughout service life. Installation is handled by licensed plumbers or water treatment technicians working on residential or light commercial filtration systems.

This cartridge is suited for standard whole-house or point-of-entry filter housings that accept 20-inch cartridges. It is commonly installed in sediment pre-filtration stages upstream of softeners, carbon filters, or reverse osmosis systems. The 20-micron rating makes it appropriate for removing sand, silt, rust particles, and other coarse suspended solids from cold or moderately warm water supplies. The non-FDA material grade designates this cartridge for general-purpose industrial and plumbing use rather than direct food-contact or potable-water-certified applications.

Installation Notes

Installation and replacement should be performed by a licensed plumber or qualified water treatment technician. Shut off the water supply and relieve system pressure completely before opening the filter housing. Inspect the housing O-ring and replace it if worn before reseating the cartridge. Follow applicable local plumbing codes and the housing manufacturer's torque and reassembly guidelines.
