Breast Pump Flange Inserts 13/15/17/19/21mm
Product description
Getting the right breast pump flange fit can make a noticeable difference to comfort during expressing, and these replacement inserts are made to help. This Breast Pump Flange Inserts set provides soft silicone cushions in five sizes, so you can fine tune the fit for more comfortable pumping sessions. It is a practical choice if you want spares for everyday use and reliable replacement parts to maintain consistent routines.
Key features

These silicone flange inserts set is designed around comfort and adjustability, with 10 inserts across five sizes. Each set includes two pieces per size, which helps you keep a spare on hand and rotate parts more easily as needed. The inserts are made from BPA free food grade silicone, described as gentle on skin while still being soft and durable for regular use.


You can choose between size options listed as 13/15/17/19/21mm or 14/16/18/20/22mm. The idea is to support a tailored fit, helping to maintain comfortable suction during pumping while reducing nipple discomfort. If you often express and rely on your equipment day to day, having multiple size inserts can be a straightforward way to experiment until you find what feels right. 🍼

What’s included and how to choose
This set includes the 10 silicone flange inserts plus two helpful bonus accessories, a cleaning brush and a measurement ruler. The brush supports hygienic cleaning, while the ruler can help you measure and work out the size that suits you best. Having both in the box makes it easier to go from identifying your likely size to fitting the inserts without extra items. 🙂

It also helps to know how compatibility is described, these inserts are intended for standard 24mm breast shields or flanges. Easy insertion and removal is part of the design, so you can swap sizes when you are adjusting to changing fit or comfort. Keep in mind that the set lists five size options, so you should compare the insert size you plan to use with your own measurement to avoid picking a poor match.


If you like a simple workflow, you can start with one size insert while keeping the other sizes as backup. You may find one size is more comfortable on certain days, especially if your needs change over time, and the extra inserts are there for exactly that reason. The extra spares also make sense if you express often and want replacement parts ready without waiting for an order.

What to know before you buy
It makes sense if you want soft replacement silicone cushions to improve your pumping comfort and help support optimal suction during expressing. You’ll like it if you regularly use a breast pump that works with standard 24mm breast shields or flanges and you prefer having multiple sizes available. It may not suit you if you are looking for compatibility outside those described shield and flange sizes. 🧼

From daily routines to frequent pumping sessions, this set is positioned as a reliable replacement option with multiple sizes included. With two inserts per size, you can maintain a spare for busy days and reduce the pressure of cleaning and swapping parts constantly. If comfort and fit are high priorities in your pumping setup, the combination of cushioning inserts plus the brush and ruler makes this a practical everyday buy for many parents.
