3G Standard Series Filter Housings

Pentair Pentek 3G Standard Series Filter Housings feature integral brackets, 20″ clear housings, and caps for differential pressure gauges. They accept standard double open end (DOE) and our O-ring sealing cartridges. The O-ring design offers enhanced cartridge sealing for critical cartridge applications.

3G Standard Filter Housings are manufactured from durable polypropylene or clear Styrene-Acrylonitrile (SAN). Reinforced polypropylene housings have excellent chemical resistance and are ideal for many residential, commercial and industrial applications. Clear sumps are manufactured from Styrene-Acrylonitrile (SAN). They offer on-site examination of the cartridge and have excellent chemical compatibility.

All are equipped with 3/4″ NPT inlet and outlet ports. 3G Standard Filter Housings are available in 10″ and 20″ lengths and will accommodate a wide range of 2-1/4″ to 3-1/8″ diameter cartridges.
