Max Water 20" Heavy Duty filter Housings O Ring.
For 20" x 2.5 Max Water whole house Filter Housings
This is a hard item to locate. I had to send pictures of the housing and area where the o ring sits before they gave me a part number. I would have liked to see it readily pictured on the web page. I got the housing from Max Water but it did take a few emails before they got the part number for me. The search should bring up all the o rings they have and a picture of the inside of the housing with a measurement We then could pick out our o ring and get it on order quickly. This water filter and housings they sell are absolutely great for price and quality. Shipping was fast. have been using my Max filters system now for 6 years great productReviewed by: Alton from Canada. on 12/14/2013
