The Tuf-Tite 20 in. Septic Tank Adapter Ring (Model TAR) is a heavy-duty, UV-resistant polyethylene ring designed to provide a secure, watertight connection between a septic tank opening and a Tuf-Tite riser or lid. 

Features:

Secure Connection: Designed to attach to the top of concrete, plastic, or fiberglass septic tanks, creating a stable and sealed interface that reduces the risk of surface water intrusion.

Durable Material: Constructed from heavy-duty, UV-resistant polyethylene, engineered to withstand outdoor conditions, moisture, and soil contact without corroding or degrading over time.

Compatibility: Made specifically for use with 20-inch diameter Tuf-Tite risers, lids, and safety pans.

Easy Installation: Features a lightweight, molded design for easier handling and installation. The use of butyl sealant tape and screws (sold separately) is recommended for a watertight seal.

Stackable Design: The adapter ring is stackable, which can help achieve a desired burial level for the septic system components.
