Enormous Hazard Potential Caused by Inferior Material - Copies of Standardized Compressed Air Fittings often show a High Potential of Cracking
Compressed air can be a dangerous medium. To prevent injuries safety precautions should be observed before usage.
Often cheap copies are offered on the claw coupling market – mostly with low grade casted material and poorly manufactured. Also hose sets are highly affected due to the use of low quality hose clamps which are assembled and supplied, mostly from the Far East. The use of such assemblies (couplings and hose clamps) contain an uncontrollable risk in operation. Due to imprecise casted hose barbs and high tolerances of hose clamps, a safe fitting on the hose barb cannot be guaranteed.
Geometric differences of the fittings are one visual part of the overall hazardous potential. More difficult to recognize is the fact, that copies are often manufactured with low quality materials and non-approved materials, i.e. white iron. The components may easily break or crack under heavy-duty utilization.
A potential risk exists here, not only for the user. The seller is also responsible, as he is liable for property damage and/or personal injury within the European Community.
To illustrate the differences between the material qualities, LÜDECKE conducted a fracture test with two hose clamps. It shows the occurring risks when using nonstandardized components.
