Product information

Find the Right Size for You

When it comes to comfortable, efficient pumping, a good fit makes all the difference.

Measurement Steps

Step 1

1. Use a ruler or tape to measure the nipple diameter (mm) at the base of the nipple and choose a suitable cover.

Step 2

2. Determine the size of a flange based on the measurement results.

Example

If the measured nipple diameter is 22 mm, it is recommended to use a 24 mm flange.

Judgment Method

Too Small

Too Small
If the size is too small, it may not be able to suck out.
