5mm borosilicate glass tubes fit in all rubber stoppers & attach to 4.8 mm plastic or rubber tubing.
This tubing fits very tightly in #3 and smaller stoppers. Use Vaseline or cooking oil to help insert the tubing into the stopper, holding the tubing with a cloth to protect your hand if it breaks.
You can easily make a bend in a 5mm glass tube by heating the tube in a candle or alcohol burner flame until the glass softens. Then carefully bend the tube to the desired shape and hold it in that position for a few seconds until the glass hardens again. Be sure to heat the glass tube over a section about 1-1/2' long to avoid crimping the tube when you bend it.
Note: HST has not tested this product for compliance with food safe requirements.
