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
