Parker T19R20A String-wound Cartridge Filter 10 Micron

Product Description

The PARKER T19R20A is a string-wound polypropylene cotton cartridge filter designed for residential and light commercial plumbing filtration applications. Measuring 20 inches in length with a 2.5-inch outside diameter, this filter delivers a 10-micron rating to capture sediment, sand, rust particles, and other particulates from water supply lines. The string-wound construction provides graduated density from the outer surface to the inner core, which improves dirt-holding capacity and extends service intervals. A polypropylene plastic core supports the filter media under flow pressure. This filter is installed by licensed plumbers and water treatment technicians in standard filter housings that accept 20-inch cartridges.

This cartridge is suited for whole-house sediment prefiltration, point-of-entry water treatment systems, and inline filtration ahead of softeners, reverse osmosis units, or other water treatment equipment. It performs well in residential main supply lines and light commercial settings where sediment loads are moderate. The 10-micron rating makes it an effective first-stage filter in multi-stage water treatment configurations. Maximum working temperature is rated at 120 degrees F, making it appropriate for cold and ambient-temperature water service lines. The polypropylene cotton construction resists mild chemical exposure common in municipal water supplies.
