The PARKER WC19R30S is a string-wound plumbing cartridge filter designed for water filtration applications in residential and commercial systems. Constructed from acetate cotton with a stainless steel core, this filter measures 2.5 inches in outside diameter and 30 inches in length, offering a 10 micron filtration rating. It handles operating temperatures up to 250 degrees F, making it suitable for hot and cold water supply lines alike. Licensed plumbers and filtration technicians install this type of filter in standard filter housings as part of point-of-entry or point-of-use water treatment setups.
This cartridge is suited for residential and light commercial plumbing systems where sediment removal is required. The string-wound construction provides graduated density filtration, trapping larger particles on the outer layers while capturing finer sediment toward the core. The 10 micron rating targets sand, silt, rust, and other particulates common in municipal and well water supplies. Its 30 inch length fits filter housings designed for longer cartridge formats, making it a practical choice for higher-volume flow applications or systems requiring extended service intervals.
Designed as an OEM-style replacement cartridge for standard plumbing filter housings that accept 2.5 inch outside diameter by 30 inch string-wound cartridges.
Installation is performed by a licensed plumber or qualified water treatment technician. Shut off the water supply and relieve system pressure before opening the filter housing to replace the cartridge. Follow applicable IPC and local plumbing code requirements for cartridge filter installations. Do not exceed the rated operating temperature of the cartridge to avoid media degradation or housing damage.
