Manufactured of hardened steel,pressure die length is critical and is determined by bending radius,bending degree and tube OD.
Formula:assuming that full 180 degree bends are required:
CLR x 3.14 ÷ 180 x 195 + 3 x tube OD
Example: 1” OD tube x 4” CLR
4” x 3.14 = 12.56” ÷ 180 x 195 = 13.60” + 3” = 16.60”
The Die should be adjustable for vertical alignment.
