Safety Notes: It is important to be safe when installing quick disconnect couplings into a pneumatic circuit.
Never install a pneumatic coupling directly into an air tool, use a piece of hose that is at least 18 in long, between the tool and the coupling, to prevent damage to the coupling.
To protect the operator, safety devices, such as a safety check valve and safety cable should be installed in case there is a hose or coupling failure.
Many competitive universal couplings are unable to match the performance capabilities of the Dixon® U series.
Although the universal coupler permits multiple series nipples to mate with one coupler, it is recommended to match like series couplers and nipples.
When using a universal coupler, the lower performance rating between the coupler and the nipple must take precedence.
Dry air: Some pneumatic applications require the pressurized air to be dried to ensure proper operation of equipment and application of product.
It is best to match like series couplers and nipples in these applications.
If it is necessary to use a universal coupler, lube the seal and valve area regularly to ensure reliable service.
