SAFE® 96 IT: 2D tubes with internal threads in the 96 SBS format. The injected TPE compression ring in the screw cap combined with the widened mouth of the tube and significantly improved sealing compared to the conventional screw caps with an O-ring. The screw cap cannot be overtightened, the permanently injected sealing ring cannot detach itself from the thread. The high screw cap is a big plus for manual handling.
