The Tuf-Tite GM Mandrel is used to create precise openings in concrete forms for installing 4-inch Tuf-Tite tank seals, ensuring strong, watertight connections in septic and drainage applications.

Purpose:

An essential tool for precast concrete manufacturers, the mandrel is used during the concrete pouring and curing process to form the correctly sized and shaped opening in the tank wall for rubber tank seal installation.

Compatibility:

Designed for use with several 4-inch Tuf-Tite tank seals, including TS-4NW, TS-4Pro, TS-4HP, and TS-4-RUBBER.

Design & Flexibility:

Engineered to deliver consistent results, Tuf-Tite mandrels can be used with forms that lift up or fold away. They are constructed from durable, non-corrosive materials to maintain shape and integrity through repeated use in demanding concrete environments.

Customization:

Mandrels can be specified based on required concrete wall thickness and whether they will be permanently mounted to the form or used as a removable component.

Reliable Connections:

By creating a precisely sized and properly positioned opening, the GM mandrel helps ensure long-term, dependable seals that meet or exceed industry standards, preventing groundwater infiltration and exfiltration—even in shifting ground conditions.
