Hydraulic Tube Bender

Mandrel Rods

Part No. — See table

Mandrel rods are for use with the HB632 Model Bender 
and Exactol Models 412/424 benders. Mandrel rods  
(as well as mandrel rod stop assembly) are required 
when using mandrels. Overall mandrel rod lengths are 
approximately eight feet. Mandrel rod diameters are  
determined by tube I.D. (See Table 3.)

Mandrel Rod Stop Assembly

For use with Model HB632 Bender

The mandrel rod stop assembly holds and supports  
the end of the mandrel rod in alignment with the tubing. 
The rod stop assembly is bolted to the other end of 
bender table. It keeps the mandrel and rod in align-
ment when mandrel bending. The stop screws can  
be adjusted for correct length and positioning of the 
mandrel in the tubing.

in different planes, and keeps out-of-plane angles  
accurate when making repeated bends. Incorporates  
a large, easy-to-read vernier dial. Maximum 3/4" O.D.  
tubing can be used if the tubing must be extended 
through the indicator. Maximum 1-1/2" O.D. tubing can 
be used if the end of tube is held in the clamp jaw.
