- Pressure gauge device, typically a small orifice, that is either screwed or pressed into the pressure gauge socket.
- Restricts the fluid flow between the pressure source and the pressure element.
- Used to reduce the effects of pressure fluctuations, frequently referred to aspulsation spikes.
- M 3.5 thread (gauge socket dependent)
- M 4 thread (gauge socket dependent)
- M 5 thread (gauge socket dependent)
- Various orifice diameters
