PIPE DIAMETERS: 8"-18" (200 mm-450 mm) PVCCast-A-Seal 603 meets or exceeds:
Cast-A-Seal 603 is a mid-range cast-in, flexible watertight pipe-to-structure connector for 8” – 18” (200 – 450mm) PVC pipe.
Mandrels and casting rings are available for PVC pipe connecting into a 48”x 5” (1200 x125 mm) manhole. It can also be used in straight-wall structures with walls as thin as 2-1/2” (64 mm) The large key-lock of CAST-A-SEAL 603 is embedded in the concrete, creating a watertight seal. After stripping, the CAST-A-SEAL 603 is unfolded to the outside of the structure and is attached to the pipe with stainless steel take-up clamps.

A flexible pipe-to-manhole connector shall be employed in the connection of the sanitary and storm drain sewer pipe to precast manholes or other structures. The connector shall be CAST-A-SEAL603 as manufactured by Press-Seal Corporation, Fort Wayne, Indiana, or approved equal. The connector shall be the sole element relied on to assure a flexible, watertight seal of the pipe to manhole. The connector shall consist of a rubber gasket and one or two external take-up clamp(s).
The rubber gasket element shall be constructed solely of synthetic or natural rubber, and shall meet or exceed the requirements of ASTM C 923. The connector casting mandrel system shall include a precisely-formed opening in the concrete for installation of a replacement connector in the event that the cast-in connector is damaged.
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 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 C923.
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 C1244 prior to back fill. Other testing shall be conducted in strict conformance with the requirements of the connector manufacturer.
