Up for sale is a new O-ring for a Berkeley jet pump hand hole cover. This O-ring fits the cover that has no name on the top as you can see in the pictures and has rounded edges. If you have the style that does have Berkeley on the top check our other listings for the correct seal. The Berkeley part number S13734. This sale is for the O-ring seal and not the cover. These are high quality American made O-rings and provide an excellent seal.   Check out my other items!
