TGL coupling

1.More shock absorption, and greater repair ability for errors of eccentricity, errors of angularity and errors of end-play

2.Superior lubricate self -motion because of industrial  plastic and metal parts

3.Outer cover is made by mold so that is easy for manufacture procedure, low cost

4.Using temperature range -20-+80

Assembling and repair is very easy, Can be used in water voltage pump, lubricate
