- The size of fitting should fit with the size of hose. It shouldn't be too tight and shouldn't be too loose as well.
- If there is rust or crack on the fitting, never use it.
- The fitting should be long enough to contain the external clamp.
- If used in high pressure and high temperature, we suggest you choose the fitting with spines. But the spines should not be too sharp, or it will hurt the inner tube of hose.
- Fasten the clamps carefully and refasten them if necessary. The deformation of clamps will cause hose leak and disconnect.
