Pentek (151120) Replacement O-Ring for Standard Housings with 3/4" NPT Connections

The rubber O-ring provides the water-tight seal between the cap and the bottom of the housing. The PENTEK-OR-241-B O-ring should be lubricated with clean silicone grease and placed in the groove below the threads of the housing to prevent a water leak. O-rings do not last forever and should be replaced any time you change the filter cartridge. The OR-241-B is an inexpensive part of your filter system and helps protect you from water damage due to a leaky seal between the housing and cap.

The OR-241-B O-Ring fits PENTEK housings #10, #12 and #20.
