Standard breast pump shields typically ship with a 24 mm tunnel diameter. When that tunnel feels too large, the product page notes that fit can feel uncomfortable or poorly fitted. Finding an appropriate flange insert size for 24mm pump flange equipment can help with comfort and fit.
This guide explains how silicone inserts reduce tunnel diameters to achieve a proper personal fit. This page uses facts stated on the product page to detail sizing, materials, and care routines.
Matching insert sizes to standard 24mm shields
Flange inserts slide directly into the standard 24 mm plastic shield tunnel, reducing the interior opening to a smaller diameter. The sizing set includes 10 soft silicone inserts in five dimensions: 13 mm, 15 mm, 17 mm, 19 mm, and 21 mm, with two inserts per size. The inserts fit most 24 mm electric and manual breast pump shields, though they do not fit 27 mm or 28 mm shields.
Constructed from BPA-free food-grade liquid silicone, these inserts feel softer than rigid plastic against sensitive tissue. Because nipple dimensions frequently change during the postpartum period, having multiple sizing options allows mothers to adapt their setup over time.
Included tools and replacement guidelines
The kit supplies a dedicated nipple measuring ruler and instruction manual to assist with size selection before and after pumping. A specialized sponge cleaning brush is included for daily maintenance. Reusable silicone inserts are dishwasher safe, and the manufacturer recommends replacing them every two months to maintain suction performance and fit.
The silicone flange insert kit for 24mm shields is currently $39.99. Users should follow the product instructions, and anyone experiencing persistent nipple pain or lactation difficulties should consult a doctor or certified lactation consultant.

- Use the included measuring ruler to check nipple diameter before choosing an insert size.
