PULSAR AWO000 20 inch Transparent Filter Housing with Blue Head, 1/2 inch NPT, Double O-Ring, for 20 inch x 2.5 inch Cartridges

In a busy workshop or a rural home with well water, sediment and particles can quickly clog appliances and reduce water quality. The PULSAR AWO000 housing accepts standard 20" x 2.5" filter cartridges, giving you the capacity to trap dirt, rust, and sand before they reach your taps or equipment. Its transparent sump lets you see exactly when the cartridge needs changing, while the blue polypropylene head provides a strong, corrosion-resistant connection. With 1/2" NPT female threads and a double O-ring seal, installation is straightforward and leak-free up to 6 bar. Whether you are protecting a whole-house system, a commercial kitchen, or a workshop supply, this housing delivers reliable filtration with minimal maintenance.

Good to know

This housing is designed for cold water use only. Always depressurize the system before opening the housing to change the cartridge. The housing is compatible with a wide range of 20" x 2.5" cartridges, including sediment, carbon block, and specialty media. For best performance, replace cartridges according to manufacturer recommendations or when pressure drop becomes noticeable.
