Cast-A-Dapter

A flexible pipe-to-structure connector shall be employed in the connection of the sanitary sewer pipe to precast tanks or structures. The connector shall be CAST-A-SEAL® 402 and CASTA-DAPTER as manufactured by Press-Seal Corporation, Fort Wayne, Indiana, or approved equal. The connector/adapter shall be the sole element relied on to assure a flexible, watertight seal of the pipe to the precast structure. The connector/adapter shall consist of a rubber gasket, a rubber adapter, an alignment plug (on multi-pipe models), and an external take-up clamp.
The rubber elements shall be constructed solely of synthetic or natural rubber, and shall meet or exceed the physical property requirements of ASTM C 923.
The external take-up clamp shall be constructed of Series 300 non-magnetic stainless steel and shall utilize no welds in its construction. The clamp shall be installed by torquing the adjusting screw using a torque-setting wrench available from the connector manufacturer.
Selection of the proper size connector and adapter for the structure and pipe requirement, and installation thereof, shall be in strict conformance with the recommendations of the connector manufacturer. Any dead end pipe stubs installed in connectors shall be restrained from movement per ASTM C 923.
The finished connection shall provide sealing to 13 psi (minimum) and shall accommodate deflection of the pipe to 7 degrees (minimum) without loss of seal.
Vacuum testing shall be conducted in strict conformance with ASTM C 1244 prior to backfill. Other testing shall be conducted in strict conformance with the requirements of the connector manufacturer.
