The reducing-diameter steel connecting sleeve is used for special engineering. One end of the sleeve is a screw thread connecting thick steel bars and the other end is a screw thread connecting thin steel bars. A steel connection sleeve with a diameter of 28 to 25 is required.

Features of reducing diameter steel connecting sleeve:

1. The diameter-reducing steel connecting sleeve can reduce the materials and is easy to operate, also they are not limited by the types of steel components.

2. The steel connecting sleeve can be prefabricated in advance, which does not occupy the construction period and has high processing efficiency.

3. The connection is convenient, fast and simple, can construct in all weather.

4. It can connect horizontal, vertical and oblique HRB335 and HRB400 steel bars of the same diameter or different diameter.
