Micro Polytube Fitting Gauge

Printing Instructions:

Print the PDF below on your printer at 100% scale. We recommend printing on 65 lb. paper or card stock if possible to provide a more sturdy gauge, however, standard paper will work. Carefully cut out the fitting gauge following the shape of the gauge as closely as possible to provide an accurate tube fit.

Using the Micro Polytube Fitting Gauge:

Place the gauge over the appropriate ear as shown in photo below. The number that is level with the top ear canal opening indicates correct polytube size. Proper tubing size selection will ensure a snug, but comfortable fit that retains its place in the ear.
