About This Product

These Ganivsor O-rings are a direct swap for that worn-out seal on your water filter housing.

You get five of them in orange, and they're the exact size you need: about 3.

9 inches inside diameter, 4.

15 inches outside, and 0.

14 inches thick.

Made from Buna-N rubber – which is tough, flexible, and handles water pressure without cracking or drying out.
They're compatible with a ton of housings: Pentek #10, #12, #20, Culligan HF-150, HF-160, HF-360, DuPont filters, Ace Hardware, American Plumber, Omnifilter, and more.

Basically if your housing uses the OR-34 or 151120 part number, these fit.
Replacing the o-ring is the cheapest way to stop a leaky filter housing – no need to replace the whole thing.

Just pop the old ring out, slap the new one in, and you're back in business.
Simple fix, big payoff.
Keep a pack in your plumbing drawer.
