View productSHURFLO 158195 vs 158196 RV Filter Housings & Service Parts
Choosing a replacement RV water-filter housing starts with the part number printed on the existing head. The SHURFLO/Pentair 158195 and 158196 are 10-inch Slim Line housings with blue bowls, black caps and ½-inch female pipe-thread connections. The important difference is the pressure-relief button on the 158195.

How the components fit into the water line
Fresh-water inlet
Flows into the filter-head inlet through a suitable ½-inch NPT connection.
Cartridge inside bowl
The selected 10-inch cartridge treats the incoming water according to its own rated performance.
Head-to-bowl seal
The housing O-ring makes the pressure seal when the bowl is correctly seated.
Outlet toward fixtures
Filtered water leaves the head for the downstream RV plumbing.
Important O-ring distinction: SHURFLO number 151121 is the Slim Line housing O-ring. Number 94-178-09 belongs to the different RV-10UC-A Waterguard filter housing and should not be selected solely because both housings use 10-inch cartridges.
Before changing a cartridge
- Turn off the fresh-water supply and pump, open a faucet to release pressure, then use the 158195 relief button where fitted.
- Provide a container beneath the housing, remove the bowl with the proper filter wrench and inspect the O-ring groove.
- Install the selected cartridge and correct replacement seal following its instructions; do not overtighten the housing.
- Restore water pressure carefully, check for leaks, flush the cartridge as directed and sanitize the plumbing on the recommended schedule.
