line.
• Hold the tubing with your two hands closely and
then bend or stretch it slowly not to make any
crack.
• Remember that the radius (R) should not exceed
70mm (Refer to Fig. 1)
Do not repeat the bending process to prevent the
tubing from cracking or crushing.
Keep in mind that the bending part should not be
cracked and make the radius (R) as long as possi-
ble (Refer to Fig. 2)`
