Housing for 4.5x20 Filter Cartridge Insert - 

Typically: Carbon, Sediment, or DI Resin Filter Cartridges

The 1 inch port allows a greater volume of liquid to pass through the cap and the the built-in pressure release button in the cap allows for easier loosening the clear sump when it's time to replace the filter. This 4.5x20 Filter Housing accommodates a wide variety of  20-inch x 4.5-inch filters of your choice.

When use for Water Purification (vs filtering) this 4 x 20in Size is preferred for holding DI Resin inside of an internal 20in Cartridge (not included).
