If you do not know what size of tube you need:
have a look near the tip of your old tubes – there should be a number usually Red on the left and Blue on the right.
Take the measurement from the top of your ear (where spectacles would sit) straight down to the centre of the ear canal entrance in mm – please see picture below. As a rough guide for PHONAK UNITRON: 26mm or less means you’ll need size 0, 27mm to 30mm = 1, 31mm to 34mm = 2, 35mm+ = 3.


Replace your thin tubes when they are KINKED, HARDENED, DISCOLOURED or BLOCKED.
