The Pentek 151122 is compatible and interchangeable with the Culligan OR-100 and W10-OR and GE WS03X10039, and is constructed from durable Buna-N which means that the 151122 is resistant to a variety of liquids and temperatures. As o-ring maintenance is vital to preventing leaks, loss of pressure and damage to equipment, Pentek recommends replacing o-rings on a regular basis especially, if you notice signs of wear or cracks.

Buy food grade silicon spray and lube the O-rings and sump threads before assembly. If lubed, the O-rings are reusable. You should still have spares. Especially if you don't have a bypass and need to get water back on in the house!
