Tuf-tite 20-TAR Septic Tank Adapter Ring 20 Inches

Product Description

The TUF-TITE 20-TAR is a 20-inch diameter adapter ring designed to mount to the top of a concrete septic tank, creating a secure transition point for attaching compatible risers and lids. Made from high-density polyethylene (HDPE), this ring bridges the gap between precast concrete tank openings and plastic riser systems. It is a critical component in septic system access installations, allowing service technicians and plumbers to bring tank access points to or near grade level without modifying the concrete structure itself. The ring ships in green and weighs 1 pound.

The 20-TAR is intended for use in residential and light commercial septic system installations where the existing tank is constructed from precast concrete. It is specifically engineered for use with TUF-TITE riser sections and TUF-TITE lids, making it part of a complete precast-compatible access system. Installation typically occurs during new system builds or during retrofits when upgrading concrete tank access to a riser-based configuration.

Key Features

• 20-inch diameter fits standard precast concrete septic tank openings

Installation Notes

Installation is typically performed by a licensed plumber or septic system installer in accordance with local onsite wastewater regulations. The tank should be pumped and all access cleared before beginning work. Sealant or butyl tape is commonly applied at the concrete-to-ring joint to maintain a watertight connection - consult local code for approved sealant types. Ensure the ring is fully seated and level before attaching riser sections.
