The Pentek 158002 5-inch housing is perfect for applications in RVs or campers, boats, small sinks, countertop residential filtration, pre- and post-reverse osmosis filtration, or humidifying systems. The Pentek 158002 Slim-Line water filter housing has outstanding chemical compatibility and is ideal for use in a variety of low flow applications. The Pentek 158002 features a pressure release button on the housing cap. Push this button before changing the filter and it will release the pressure in the sump and make it easier to take off, making changing the filter quick and easy. The water filter cartridge is not included with the housing--this allows you to purchase the best water filter for your water supply. Leaking is prevented by the dynamically sealing O-Ring. The O-Ring should be replaced periodically to prevent leaks. Two number 5 housings can be connected with a pipe nipple or pipe union. There are several pipe nipples available that can be used to connect two number 5 Standard Housings. Use the NP-38 pipe nipple to connect two number 5 Housings with 3/8-inch inlet/outlets.
