A-Lok - Model Inserta-LOK -Flexible Pipe to Manhole Connector

• Functions on pure compression making field installation quick and easy. Clean and lubricate both connector and pipe, center pipe in connector, and insert
• The connector provides a tapered profile which enhances coupling characteristics by allowing final compression to be gradual, thereby reducing the overall coupling force
• Can be installed in a precision cast or cored opening as a mainline connector for new construction, a retrofit or a tie-in for new construction
• Provides over 7° of omnidirectional deflection to eliminate infiltration and shear due to settlement or ground movement. This flexibility permits immediate backfill enhancing project safety, and overcoming the problems normally encountered with water, running sand and other unstable trench conditions

A flexible pipe to manhole connector shall be used for sanitary and drain pipe penetrations into precast concrete manholes and structures. The connector shall be the Inserta-LOK Connector as manufactured by A-LOK Products, Inc., Tullytown, PA or approved equal.

The design of the seal shall provide a flexible, positive watertight connection between the pipe and concrete wastewater structures. The connector shall assure that a seal is made between (1) the connector and the structure wall, (2) between the connector and the pipe. The seal between the connector and the structure wall will be made by pure compression of the resilient material against the wall of the structure. The seal between the connector and the pipe will be made by pure compression of the resilient material against the outside diameter of the pipe. The connector shall be the only component to affect the seal between the pipe and structure.

The connector shall be extruded and vulcanized from materials whose physical/chemical properties meet or exceed the physical/chemical resistant properties outlined in ASTM C-923.

The connector shall be the size specifically designed for the pipe material being used and shall be installed in accordance with the recommendations of the manufacturer.
