NB fittings are designed for use with nominal bore (NB) pipe systems, providing reliable and compatible connections across a wide range of industrial and mechanical applications. Nominal bore refers to the approximate internal diameter of a pipe, making NB fittings a standard choice for many pipework systems used in the UK and internationally.

These fittings are commonly used to connect pipes, valves and equipment in systems handling water, air, fuel and other fluids. Their standardised sizing ensures consistent compatibility across different components, making them a practical and widely used solution in both new installations and maintenance work.

Our range of NB fittings includes a variety of components such as elbows, tees, reducers, caps, sockets and adaptors. Available in materials including stainless steel for corrosion resistance, mild steel for strength and cost-effectiveness, and galvanised steel for added protection in outdoor environments, these fittings can be selected to suit different operating conditions.

NB fittings are widely used across industries including manufacturing, construction, utilities, agriculture and maintenance, where reliable pipe connections and system compatibility are essential.
