Description: SureFlex couplings offer torsional flexibility by using rubber or neoprene. Some coupling models also have Hystrel sleeves. They have a unique 4-way flexing action, which is efficient in shock absorption and even end float. These couplings do not require maintenance and lubrication, which means they offer the best performance without producing a loud noise.
