Parker 19R20S String-wound Cartridge Filter 10 Micron

Product Description

The PARKER 19R20S is a string-wound cartridge filter designed for plumbing and water treatment applications requiring reliable sediment removal at a 10 micron rating. Constructed from FDA-grade cotton wound around a stainless steel core, this filter measures 2.5 inches in outside diameter and 20 inches in length. It handles process fluid temperatures up to 250 degrees F, making it suitable for both cold and hot water service. Licensed plumbers and water treatment technicians install this style of filter in standard filter housings sized for 20-inch cartridges.

This filter is suited for residential and light commercial water filtration systems where sediment, dirt, rust, and particulate control is required. String-wound construction provides graded density filtration, capturing larger particles in the outer layers and progressively finer particles toward the core. Typical installation points include pre-filtration ahead of water softeners, reverse osmosis systems, and other sensitive downstream equipment.
