Precision Orifices


Precision orifices from Bucher Hydraulics are manufactured with close tolerances (+0.02/-0.01) and thus guarantee high flow accuracy. Each orifice is marked with its respective orifice diameter. The orifices are used for throttling and controlling oil flows in all hydraulic applications.

We manufacture burr-free precision nozzles from thread M3 and bore diameters from 0.3 mm. We work primarily with free-cutting steel, other materials are available on request.
