Plastic tube works as special high way for ink & make up, to deliver them from liquid tank or reservoir to another part of the inkjet printer system. It seldom goes wrong, but when you need to replace the tube, please noted that there are two types of tube with different diameter, one of 1/2” the other of 3/4”. Or you could take a picture of your printer ink system and point out which section of tube you are going to replace, we will send you the right size tubes.
Any questions, please feel free to contact us.
