Tube Installation And Removal
Tube installation
Just insert light couplings (one-touch couplings) up to the tube end to fix the lock claw in place, and then seal the elastic sleeve to the outer radius of the tube.
When installing, refer to the safety precautions on listed products (6. Cautions when installing tubes).
Removing tubes
When removing tubes, press the opening ring to open the lock claw and release the tube.
Be sure to stop the air when removing them.
Warning
1. Do not use for purposes other than those defined for the products by series. Please inquire about use of products for other than their specified purposes.
Warning
1. Tighten the partition nuts for partition unions (PM), partition unions P (PMP) and partition union elbows (PML) to within the specified tightening torque range.
Partition nuts torque value
| Product Name | Fitting Size | Tightening Torque | |
|---|---|---|---|
| Partition Unions (PM) | Partition Unions P (PMP), Partition Union Elbows (PML) | ||
| Tube Fitting | 4 | 12.0 to 14.0 N⋅m | 0.4 to 0.6 N⋅m |
| 6 | 18.0 to 21.0 N⋅m | 0.9 to 1.1 N⋅m | |
| 8 | 18.0 to 21.0 N⋅m | 1.1 to 1.3 N⋅m | |
| 10 | 19.0 to 21.0 N⋅m | 2.3 to 2.7 N⋅m | |
| 12 | 19.0 to 21.0 N⋅m | 2.7 to 3.3 N⋅m | |
| 16 | 42.0 to 54.0 N⋅m | - | |
| Tube Fitting Mini | 3 | 2.5 to 3.5 N⋅m | - |
| 4 | 5.0 to 7.0 N⋅m | ||
| 6 | 12.0 to 14.0 N⋅m | ||
2. Tightening partition nuts may cause deformation of the object being tightened or cause oil to adhere to its surface, which in turn will loosen the partition fixing area.
3. Our air pressure pipe coupling anticipates that tubes installed before use, and thus if air is applied when tubes are not attached to flashings, etc., the elastic sleeves may be ejected outside of the product body.
Please refer to the manufacturer's catalog for safety precautions other than those listed above.
