Help me find o-ring for 20" filter housing.

[tjl5709]

My well system has a 20" x 2.5" filter housing. Similar to the pentek 150009,. but it has a white housing, and the o-ring from what I measure is 3.5" ID and it is 1/8" thick. The pentek uses a 4" o-ring and it don't work.

No labels on the housing.

Any ideas folks?

Unfortunately, o-rings are very dependent on the filter and the manufacturer. Without knowing this, it is very hard to know what you need. The standard sizes for Pentek are 151120 (approximately 4 1/8") and the 151121 (approximately 3 5/8"). You would want the 151121, however we cannot guarantee this will work but this is the closest to what you have. If an O-ring is unable to be located, unfortunately, a new system will be needed.
