Product Description

Product Description:

Air Hose Coupling are recommended to be used in the transfer of air and or water. 

The application should be in an open system where the air or water is in motion (dynamic) and not in a closed pressurized (static) condition. This dynamic application involves continuous flow, therefore, back pressure would be relieved by the very nature of the application. 
The applicable system should contain pressure relief valves to relieve any excess pressure. 
Safety clips and safety cables should be installed on either side of the coupling connection.
