No-Hub Couplings
Standard Couplings
CISPI Standard 310: Specification for coupling for use in connection with hubless cast iron pipe and fittings for sanitary and storm drain, waste, and vent piping application (Regular hubless coupling)
Scope: The purpose of this specification is to establish criteria for material dimensions and tolerances for one type of coupling used in hubless cast iron soil pipe and fitting for sanitary and storm drain, waste and vent piping applications.
ASTM C 1277: Specification for shielded couplings joining hubless cast iron soil pipe and fittings
Scope: This specification covers the evaluating of the performance of shielded hubless couplings to join cast iron soil pipe and fittings.

Standard Couplings
Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. They are normally installed using a torque wrench.
Medium and Heavy Duty Couplings
Intended for use with DWV systems, no-hub couplings are used to join cast iron soil pipe that does not have the traditional Hub and Spigot. They are normally installed using a torque wrench. Generally, they have more clamps and provide a greater band load than standard no-hub couplings.
