Ductile Iron Fittings - Tooth Gasket Restrained Joints
Features
- Can be used on any push-on joint socket and spigot fitting.
- 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 fitting, the steel teeth allow the spigot to be pushed into the socket.
- Once the spigot is fully inserted, the teeth bite into the spigot and restrict it from coming out.
- This specially designed gasket performs the dual role of water sealing and restraining.
- After assembly, it is recommended to pull back the fitting a little bit, to ensure engagement of teeth.
