Brass Nipples
A brass nipple is a brass fitting with male threads on both ends and a hexagon in the middle, connecting two female-threaded parts.
It is used as an intermediate piece at valve, meter, filter and manifold connections. It is supplied in 12 sizes from 1/8″ to 4″.
Main Applications
- Short connections between valves and fittings
- Water meter groups
- Valve arrays on manifolds
- Filter and pressure reducer connections
- Compressed air equipment
- Instrument connections
