NSF grease is needed for installation of the O-ring and it was not provided so no possible to install without it

Bought these for our whole house water system filter bc we have had them in the past they work great and are easy to install into the filter housing. We just put some grease on it to make it easier for removing when the time comes to change out the filter

Used on my water filter canister pentec big 10. Works just fine. No leaks. They are a fraction of a millimeter thinner than the original but it is hardly noticeable and they work just fine.

Perfect fit in my Pentek 4 water filter housing. Don't forget only use silicone grease on the o ring because any other lube can soften the rubber and it will stretch out out shape.

These O-rings were the perfect OEM fit. Make sure to lubricate your new O-ring. I have found that lubricating the threads prevents the plastic on plastic binding and provides a better leak free installation and easy removal of the plastic filter basket.
