This GUIDI bronze hexagon nipple is a straight, non-reducing pipe fitting with male threads on both ends. It is used to connect two components with compatible internal pipe threads of the same nominal size, such as valves, filters, skin fittings, and other fittings.
The fitting is manufactured from bronze and is suitable for marine piping systems, including water, cooling, hydraulic, HVAC, and desalination installations. It can be used in systems with salt water or fresh water, as well as in installations below the waterline, provided the media, pressure, and temperature are compatible with the rest of the system.
Both ends feature tapered BSPT pipe threads according to EN 10226-1, with BS 21 as a reference. BSPT and NPT are different thread systems and should not be considered directly compatible. The assembly must be performed using appropriate thread tape or thread sealant, and the connected components must have a compatible thread type, standard, and seal.
The central hexagon provides a secure grip for a wrench, making installation simple. The fitting has a straight, through-bore channel, and the non-reducing design maintains the same pipe dimension throughout the connection. It is available in several nominal thread sizes with variant-specific measurements for total length, wrench size, A-dimension, F-dimension, bore size, and weight.
