15. POSSIBLE CAUSES OF LEAKS
1. Tube inserted into the fitting creased or damaged.
2. Tube not pushed fully home in the fitting.
3. Non-standard connection between tubes or non-matched sizes.
4. Incorrect installation fixing.
5. Connection made to the fitting by the operator using incompatible products.
6. Installations subject to mechanical stress, e.g. assemblings non properly lined up.
7. Other objects anchored to the structure housing the fitting.
8. Thermal expansion not compensated for by adequate fitting techniques or equipment.
9. Freezing of the installation.
10. Pressure or temperature specifications outside those indicated in the conditions of use.
11. Unforeseen external causes such as accidental impacts or sabotage.
12. Fittings welded by the operator rather than pressed.
13. Double pressing of the fitting.
14. Missing observance of the minimum distance between two fittings.
15. Poor storage and handling of the fittings with deterioration of the o-ring, caused by external agents such
as light, temperature, dirt, ozone etc.
16. Mechanical damage of the fitting (cuts, bending, crushing).
17. Replacement of seals or spare parts not supplied by Eurotubi.
18. Tearing of the o-ring, for example caused by pipes not properly deburred.
19. Incorrect tube insertion causing the o-ring to become dislodged from its position.
20. Use of unsuitable o-ring lubricants, it is possible to use only talc and water.
21. Internal or external liquids not compatible with the o-ring material composition.
22. Pressing carried out with worn pressing jaws.
23. Use of a pressing machine no longer capable of exerting sufficient force (the result of wear and tear,
poorly performed or lack of maintenance).
24. Pressing jaws not correctly positioned in relation to the fitting when pressed.
25. Pressing jaws not fully closed.
26. Use of non-standard pressing jaws or jaws certified for other profile types.
16. GUARANTEE
The use of original Eurotubi Pressfittings, with the correct pipes and approved pressing tools, coupled with
strict adherence to the technical instructions given for both the design and installation of the system, will
guarantee the longevity of the system.
Damage arising from material or manufacturing defects in the fittings is fully covered by insurance.
