Usage Example
How To Attach And Detach The Connecting Part
1. How to attach/detach the tube
(1). Tube installation
The tube fitting (quick connect fitting) has a lock claw that secures the tube by simply inserting it to the tube stop, and an elastic sleeve that seals the circumference of the tube.
When installing the tube, refer to "6. Cautions for installing the tube" in the digital catalog.
(2) Tube removal
To remove the tube, push the release ring to open the lock claws and pull out the tube.
Be sure to stop the air before removing.
(1). Screw tightening
There are two types of screw tightening: one that tightens the hexagonal outer diameter with a wrench or impact wrench, and one that tightens the hexagonal inner diameter with a hex key (allowing a smaller space between fittings).
When tightening, refer to Table 2. Tightening torque, Sealock color, and gasket material in "8. Precautions for mounting the main body" in the digital catalog.
Product Feature Details
Comparison Chart: Mini vs. Standard
Easy tube attachment and removal even with ultra compact size. The release ring features an oval shape.
Since its initial release, the Mini has featured a release ring with an easy-to-press oval shape.
The standard uses a circular release ring, while the mini uses an oval-shaped release ring. Optimized for operability.
Quick connect fitting available for ultra-fine diameter tube piping.
The ⌀1.8 (1.8 mm diameter) and ⌀2 (2 mm diameter) sizes are ideal for piping to compact actuators, etc.
