Brass Hex Nipples

A brass male-female adaptor has one male-threaded end and one female-threaded end. Equal-size types extend a threaded connection, reducing types provide a size transition.
It is used for valve and tap extensions, changing the thread gender at a device port and instrument connections. 13 sizes between 1/8″ and 1 1/2″ are available.
Main Applications
- Valve and tap extensions
- Converting a male port to a female connection
- Instrument connections
- Adjusting combi boiler and water heater connections
- Compressed air equipment adaptors
- Adjusting connection depth in walls
