![]() If bend direction for either 45° or 90° bend must be reversed, subtract the “gain” amount listed in table 11. ![]() Thus, if you unknowingly make a reverse bend of 90°, you will trap the gain, in table 11 (approximately one tube O.D.) and increase your length between bends by that amount. If you reverse the direction of bending (bending towards instead of away from the original starting end) you will “trap” the stretch. A good “rule of thumb” for most standard tubing materials and radius blocks is that the tubing will stretch approximately one tube diameter for each 90° bend.Īlways try to bend in the same direction – away from the original starting end. This is because it takes a curved shortcut across the inside of the angle. When bent, tubing seems to stretch or pick up length.
