I found it at a specialized hardware store. The price is cheaper than Pushfit fitting.
Housing screw:
– M6, pitch is 0.9mm
– Length is 6.00 mm
Coupling housing width: 10.00 mm
Locking screw: 8.00 mm
It holds PTFE tube (OD 4.00 mm, ID 2.00 mm) firmly. It eliminates the tube movement once it's secured by the locking screw.
The red filament is 1.75 mm PLA. There is no restriction against filament movement.
This kind of fix becomes thing of the past.
