Maeda Koki MKCT Type Oil Signal

Made in Japan
Manufacturer: Maeda Machinery Research Institute Ltd.
Model: MKCT Type
Features
- A transparent tapered tube is used, so the flow rate can be checked by looking at the relative position of the ball (or float) and the red line .
- With protective cover
- The metal protective cover reduces the possibility of damage from external impacts.
- No need to worry about the installation direction
- A spring is used inside, so the installation direction can be freely changed, such as upward, downward, or sideways.
