Important notes:
- Conical gas thread with sealing in the thread, according to standard NF EN 10226.
- The maximum permissible displacements indicated do not apply simultaneously.
- Axial stiffness is measured without pressure for an axial displacement of 1 cm.
- DN 20/25/32: same mounting template. DN 40 and DN 50: specific templates — see diagrams.
