The Thread of Nozzles

NPT and BSP Threads

RELAB has been manufacturing various spray nozzles and fittings with different thread standards: Metric and Imperial. They are the most commonly used in our products.

UNC, UNF and UNEF Threads

The Unified Thread Series was agreed on by the United States, Britain and Canada in 1949 to obtain interchangeability. Recently, modifications have been made to the original specifications for ease of use.

Inch and Metric Thread Standards

Inch and metric threads are widely used in the field of nozzle manufacturing. We often make different nozzle threads to match the spray system from different countries.

PT, NPT, G, R and Rs Threads

At RELAB factory, when we produce the spray nozzles or other threaded workpieces, we are often necessary to consider requirements for thread standard. If the customers use an British system, we must make the nozzle with BSPT thread; if the customers use an American system, we must consider making the nozzle with NPT thread.
