1. Workability has been improved because it can be connected by simply tightening the wheel after hooking.
2. It can be used under internal pressure conditions from vacuum to 0.2MPa, but when using it under internal pressure, select the nut type.
3. Due to the spring steel adopted for the belt part, deformation does not occur even when it is attached/detached repeatedly.
| pressure | Type | Size | Materials | Recommended tightening | Baking |
|---|---|---|---|---|---|
| internal vacuum | Knob (common product) |
φ40wheel | Nylon resin | Retightening after vacuuming (internal pressure unacceptable) |
Unacceptable |
| internal vacuum/internal pressure | Nut (optional) | M6 high nut | C3604 | Tightening at a torque of 4.0N·m | Acceptable |
