The Tuf-Tite® TS-RB4 Rubber Boot Seal is an open-ended rubber boot seal used for making secure, watertight connections when a pipe penetrates a septic tank wall. It is designed to accommodate the movement and settling of the ground without compromising the seal's integrity. Note that while the query requested the "-CE" (Closed End) model, this part number is for an open-ended application, typically used with a clamp for installation. The closed-end equivalent is the TS-402-CE model.
