A Closer Look

Tube Types

Tube OD is the first consideration in determining the proper model of the 12 series tool. Using the chart below, select the Collet size closest to your tube "OD". The collet size is then used to determine the model number. Then find the seal nearest the tube ‘’ID’’. The seal and collet sizes then follow the model number to complete the tool description.
