Culligan OR-34 Whole House Filter O-Ring
The Culligan OR-34A O-ring 2-pack includes O-rings labeled A and B. If you are looking for the O-ring from the old OR-34 single O-ring pack you need the O-ring tagged with a B, which fits housings that use a 4 1/8-inch outside diameter O-ring. The O-ring tagged with an A fits housing that use a 4-inch outside diameter O-ring. Over time the O-ring that comes with your filter housing will wear down and may leak so you should replace your O-ring after every 3rd filter change.
The Culligan OR-34 fits Culligan and Ace whole house water filter systems including HF-150, HF-160, HF-360, 45025, 46764, and 49560.
The OR-34 is compatible with the following:
