Connection of almost any device (with the exception of welded ones) to the pipelines of liquid, pneumatic or gas systems is often carried out using unions with union nuts.
To install a domestic hot water boiler or install a water meter, you will need to use threaded fittings with a union nut and a sealing gasket. At first glance, this is a simple quick-connect solution for many devices, but in reality, there can be at least two ways to produce fittings with union nuts: The first is the turning of a hexagonal workpiece, followed by milling parts.
This method makes sense in a situation where it is necessary to urgently produce several sets of fittings with specific requirements. In this case, it is necessary to have the material (blank), machine park and specialists of the appropriate qualification. The price of the fitting itself with a union nut will be quite high due to individual (single) production. The second is hot stamping of workpieces with subsequent turning.

This is a more expensive production option in the initial situation (special molds need to be made), but for larger volumes, the unit cost will be significantly lower than a custom-made choke. The pleasant moment is the fact that you pay only for the actual weight of the product (excluding waste for processing) and the parts themselves are more durable due to the compaction of the material during stamping. How to choose the most suitable of the two possible manufacturing methods?
It all depends on the required volume of the manufacturing order - if you need a dozen sets of this connecting fitting, the first option will do. Then you need to look for brass rolling of the appropriate size and a good turner. If you need to order the manufacture of several thousand brass fittings with union nuts, contact the enterprises specializing in hot stamping and processing of brass parts, one of which is STA.
