Competitive brass hydraulic fittings processing Competitive brass hydraulic fittings processing
The correct quality-price ratio when producing brass hydraulic fittings, often called generic fittings, can only be obtained with cutting-edge machines combined with purposely-studied tools that make it possible to carry out multiple processing in a single operation. The study of the tool shape [...]

Pressure reducers for high pressure gas Pressure reducers for high pressure gas
A specific section of the GNALI BOCIA gas catalogue is dedicated to pressure reducers, devices that lower those high pressure values found, in particular, in tanks where the internal pressure is particularly high and cannot be handled by a normal regulator. Made with a brass or zamak body and [...]
