• Cast-A-Dapter gasket for pipes to manholes

Cast-A-Dapter

Cast-A-Dapter is a rubber adapter that provides flexible, watertight sealing of single or multiple pipes and conduits into on-site treatment tanks.

Category:

Used with our Cast-A-Seal® 402 cast-in flexible connector, Cast-A-Dapter is available in a wide variety of pipe diameter
combinations to meet the needs of any tank design or specification.

Features and Benefits

  • Easily seals multiple pipe and conduit entries permanently and flexibly.
  • Includes Alignment Plug (multi-pipe models only) to eliminate pipe spread.
  • Eliminates infiltration and exfiltration.
  • Improves on-site system performance and minimizes maintenance.
  • Protects groundwater from unintended discharges.
  • Allows Cast-A-Seal 402 to be used with a wide variety of in-tank systems and applications.

Used with CAST-A-SEAL 402, CAST-A-DAPTER seals to:

  • 13 psi in straight alignment
  • 10 psi at 7 degrees (min.) deflection
  • 10 psi with full shear deflection
  • and meets or exceeds all requirements of the following
    Standards, Codes, Specifications and/or Test Methods:

  • ASTM C 923 Standard Specification for Resilient Connectors Between Reinforced Concrete Manhole Structures, Pipes, and Laterals
  • ASTM C 1644 Standard Specification for Resilient Connectors Between Reinforced Concrete On-SIte Wastewater Tanks and Pipes
  • ASTM C 1478 Standard Specification for Storm Drain Resilient Connectors Between Reinforced Concrete Storm Sewer Structures, Pipes and Laterals
  • ASTM C 1244 Standard Test Method for Concrete Sewer Manholes by the Negative Air Pressure (Vacuum) Test
  • IAPMO/ANSI Z1000 Standard for Prefabricated Septic Tanks
  • IAPMO/ANSI Z1001 Standard for Prefabricated Gravity Grease Interceptors
  • NPCA Best Practices Manual for Precast Concrete On-Site Wastewater Tanks
  • NOWRA Model Code Framework
  • Florida Department of Health Product Approval

    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.
