ASTM F 2946 : 2012 : R2021

1.1This specification covers the minimum performance and material requirements for a three piece tee connector for connection between plastic pipe and insitu pipes, manholes and wastewater structures in sanitary and storm sewer applications.

1.1.1The three piece seal system consists of a 4 through 30-in. PVC (polyvinyl chloride) hub pipe, an elastomeric seal (gasket) and a mechanical band (Fig. 1). The system is installed in either a bored or cast hole opening in the host pipe or structure to a specific dimension that corresponds to the combined diameter of the PVC pipe outside diameter/tolerance and the elastomeric seal thickness.

1.2These tee connectors are designed to provide a non-pressure (gravity flow) watertight connection between the incoming pipe and an insitu pipe or manhole/structure to the limits defined in this standard.

1.3 The following precautionary caveat pertains only to the test methods portion, Section 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use.
