Detailed Safety Instructions


1.High Rotary Joint series can bear a certain amount of radial load. However it may reduce the lifetime of the product. Be sure to verify the resistance when the load is large.

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.
