Corrugated Pipe Adapter

The corrugated pipe adapter gasket is a rubber adapter ring that fits closely into the corrugation of the pipe, creating a smooth exterior diameter for connecting the pipe to a manhole or other types of structures.

Used in wastewater or stormwater systems

How It Works

The adapter is stretched over the pipe like a rubber band and the lobe then fits snug inside the valley of the corrugation.
The pipe is inserted into the structure under the clamp area of the flexible connector.
The series 304 stainless steel take-up clamp(s) is tightened around the connector creating the seal between pipe, adapter and structure. Always use a T-handle torque wrench set to 60-inch pounds when installing the take-up clamps.

Why It's Better

Easily installed with no special tools or equipment needed.
Creates a smooth rubber seal between the pipe corrugations and the connector.
Wide range of uses for both sanitary and storm water applications.
Contractor can save time and money by backfilling immediately.

Where To Use

Manholes
Wet wells
Square pump and lift stations
Stormwater structures
On-site treatment structures
Junction chambers
Grease interceptors
Vaults

ASTM C 1478 – Standard Specification for Storm Drain Resilient Connectors Between Reinforced Concrete Storm Sewer Structures, Pipes, and Laterals
ASTM D 2321 – Standard Practice for Underground Installation of Thermoplastic Pipe for Sewers and Other Gravity-Flow Applications, Section 7.10 – Manhole Connections

A rubber corrugated pipe adapter and flexible boot-type connector shall be employed in the connection of the ADS corrugated storm or sanitary sewer pipe to precast manholes or other structures. The adapter shall be ADS Pipe Adapter as manufactured by Press-Seal Corporation, Fort Wayne, Indiana, or approved equal. The flexible boot-type connector shall be PSX: Direct Drive as manufactured by Press-Seal Corporation, Fort Wayne, Indiana, or approved equal.

The adapter shall be the sole element relied on to assure a flexible, watertight seal of the pipe to the flexible connector and through the connector to the manhole or other structure. The adapter shall consist of a rubber gasket which fits closely into the corrugation of the pipe.

The rubber gasket element shall be constructed solely of synthetic or natural rubber, and shall meet or exceed the requirements of ASTM F 2510, ASTM C 1478, and ASTM D 2321, Section 7.10 – Manhole Connections.

Selection of the proper size adapter for the pipe requirement, and installation thereof, shall be in strict conformance with the recommendations of the adapter manufacturer.

The finished connection (pipe adapter and flexible boot-type connector) shall provide sealing to 10.8 psi (minimum) and shall accommodate angular deflection of the pipe to 7 degrees (minimum), and diametric deflection of 5% (minimum) with no loss of seal, as documented by test reports required by ASTM F 2510 and ASTM C 1478.

Testing of installed adapters and connectors shall be conducted in strict conformance with the requirements of the adapter and connector manufacturer.
