About Hexagon nipples
Double threaded nipples connect two female threaded parts through one piece carrying a male thread at each end. Sizes run from R 1/4 to R 3 male, and reducing versions bring two sizes together, for example R 1/2 to R 1/4. The material is black malleable cast iron B350-10 design symbol A.
What matters when choosing
- Thread size: R 1/4 to R 3 male, governed by the nominal size of the two connections.
- Equal or reducing: where thread 1 and thread 2 differ, the nipple also handles the change in cross section and saves a further fitting.
- Thread standard ISO 7-1: both mating parts must follow this standard for the tapered joint to seal.
- Material version: black malleable cast iron B350-10 design symbol A is standard, hot dip galvanised versions are intended for damp surroundings.
- Price bracket: from 0.89 to 27.99 euro the price mainly tracks the size, which counts on larger quantities.
Typical applications
- Joining two sockets or valves in pipework construction
- Compressed air distribution with take-offs from manifold blocks
- Water and heating installation in building services
- Connecting shut-off valves and filters to a line
- Maintenance work when a transition between two thread sizes is missing
Threads comply with ISO 7-1 and the material is black malleable cast iron B350-10 design symbol A throughout. The group holds 54 articles and covers equal as well as reducing sizes from one series.
