Double Filter Cartridge Housings


Our Double Filter Cartridge Housings consist of two filter housings mounted on a single double bracket. Double or ‘Duplex’ filter housings are a convenient option for customers looking to mount a series of filters in succession, without the use of connectors. The clear finish allows for easy monitoring of filter cartridge life, making it an excellent choice for a number of applications including drinking water and sediment control.

Why Choose Our Double Filter Housings?

  • Suitable for all 10” or 20” regular diameter filters
  • Easily mount a series of filters in succession
  • Clear housings for visual checks of cartridge
  • High quality brass ports for added strength

These Double Filter Housings are manufactured from WRAS approved materials, ensuring they are suitable for use with drinking water. The housings feature a durable 3 piece design consisting of a head, bowl and locking ring which ensures a positive and leak-free seal.  Complete with a spigot in the head and the base to make locating the filter cartridge easier and for the secure fitment of double open ended (DOE) cartridges. We supply a range of fittings that are compatible with these housings, allowing you to adapt the inlet and outlet to standard pipework sizes such as 15mm or 22mm.

Sarah at Ultra Soft Water Softeners helped to identify a suitable JG replacement connector for tri-flow water filter system. She went extra mile to make sure it was the right one. Really pleased with the service. Even called me to ensure the item was delivered and worked which it did. Thank you & well done.
