A G.I. hex nipple has a taper male thread on each end and a hexagon in the centre, so it can be tightened with a spanner rather than pipe grips. It connects two female-threaded parts, such as a valve to a tee or an elbow to a socket, with no gap between them. In EN 10242 the hex nipple is pattern N8. Its threads follow ISO 7-1, and the length of thread that engages depends on the gauge length for each size.
Hamza Fasteners supplies galvanised hex nipples from 1/4 inch to 4 inch in BSPT and NPT threads. Barrel nipples cut from G.I. pipe are also available in standard lengths. Plumbers and fitters use them on valve sets, pump connections, manifold builds and gauge assemblies. Send size and thread to our Deira, Dubai counter for a quick price.
