Detailed Safety Instructions


1.Avoid excessive radial load. It may reduce the lifetime of the products. The performance and lifetime of the product may be affected.

2.Use polyurethane tube for the high rotation applications. Hard tubes like nylon base may cause radial load to the fitting.

3.Tightening with excessive torque may cause a deformation of the metal hexagonal-column, leading a poor rotation or a fluid leakage.
