Detailed Safety Instructions
Caution
1.Make sure to insert the barb into a tube up to the barb end. Inadequate insertion may result in the escape of the tube and a fluid leakage.
2.Be sure to place Tube Clamp Sleeve on the edge of outer tube when using Vacuum Tube "UD" with this product. There is a possibility to cause the escape of tube and a fluid leakage without Tube Clamp Sleeve.
3.Tighten the nut by hand until it touches the metallic body. Inadequate tightening may result in the escape of the tube and a fluid leakage.
4.In case of using non-PISCO brand tubes, make sure the tolerance of the outer / inner tube diameter is within the limits of the following table.
