The Tuf-Tite BSM-4 Mandrel is used during the concrete casting process to create a precise, round opening for watertight pipe connections using Tuf-Tite rubber boot seals. It provides the proper form and support while concrete is poured and cured, then is removed to leave a correctly sized and positioned opening.
Purpose:
Provides the form and support needed during the pouring and curing of concrete septic or water tanks. Once the concrete sets, the mandrel is removed, leaving a clean opening ready for rubber boot seal installation.
Compatibility:
Designed for use with Tuf-Tite 4-inch rubber boot seals, including TS-402 and TS-RB4 models, such as the TS-RB4-CE closed-end variant.
Functionality:
Ensures proper alignment and sizing for a reliable, watertight seal between the pipe and the concrete tank wall.
Durability:
Constructed from non-corrosive materials suitable for repeated use in demanding concrete casting environments.
