Ductile Iron Pipes -  Tooth Gasket Restrained Joints
    
    
    Features 
    
- Can be used on any push-on joint socket and spigot pipe
- Needs specially manufactured steel teeth inserted gasket in place of a normal gasket
- The gasket has to be set in the socket groove like any other gasket
- Like any other pipe, the steel teeth allow the spigot to be pushed into the socket
- Once the spigot is fully inserted, the teeth hold the spigot and restrict it from coming out
- This specially designed gasket performs the dual role of water sealing and restraining
