Nor do you want anything else in those pathways. If the ends of your tubing are open or have spent significant time open, they may already be contaminated. Every time you cut off a piece of tubing for use, you should close off the end of the unused roll to prevent stuff from getting in there. I wince every time I see a piece of open ended tubing in the bottom of the parts tote. Why take chances?
