1) Drive Extensions:
Are used with universal joints and parallel gear train drives as well as extension couplings for extending expander mandrel reach through water legs, headers etc.
2)
Extension Coupling:
Are available in plain or reducing type and are used to connect drive extension, mandrels, and universal joints.
3)
Universal Joints:
Female x Female are most common and are used to create flexibility in reaching hard to get to stop.
Double Universal Joints:
Allow more deflection than Female x Female universal joints.
Male x Male: are suitable for use in sugar heater headers.
4) Parallel Gear Train Drive: Have high strength gears with bronze bushings to expand tubes in hard to reach places.
5)
Right Angle Worm Gear Drive:
Used for operating in very confined areas of boiler headers.Has a one piece construction for maximum life.
6)
