The Dixon FM25F20T brass hydrant adapter joins a 2-1/2-inch male NST (NH) connection to a 2-inch female NPT connection. Its female NST end and male NPT end provide a rigid transition between two different thread systems.
Choose this hex adapter when both mating connections match those sizes and thread types. Nominal size alone does not establish compatibility: identify the thread on each side before ordering.
| Feature | Benefit |
|---|---|
| Female NST to male NPT | Adapts the specified fire-hose connection to a pipe-thread connection without changing the mating equipment. |
| Hex body | Provides wrench flats for installing the rigid adapter. |
