## Description

These 19mm flange inserts are soft silicone accessories for breast pumps, designed to sit inside 24mm shields to improve comfort and fit for many wearable and electric models. They help reduce nipple friction and can make pumping sessions gentler, especially when used with a small amount of nipple balm or coconut oil.

## Key points

Made from transparent BPA free silicone, the inserts are easy to clean with warm soapy water and a rinse. The pack contains six pieces, so you can keep spares between washes. According to the manufacturer guidance, replacing the insert every one to two months helps maintain hygiene and reliable performance. Note that some users may notice temporary nipple swelling during pumping, so check the nipple appearance while in use and stop if there is discomfort.

## Specifications

- Name: Flange Inserts for Breast Pumps
- Size: 19mm
- Compatibility: fits most 24mm shields
- Material: Silicone
- Quantity: 6PCS

## Benefits

These inserts aim to improve seal and comfort when a standard flange feels large or causes rubbing. They can be a cost effective way to adjust fit without buying new flanges, and the transparent silicone makes it straightforward to spot wear or residue.

## Getting the most from it

It makes sense if you want a simple way to refine your pump fit without changing the main shield. Try a small smear of coconut oil to ease insertion and reduce friction, and rinse inserts soon after use. Ten in mind that they only work with 24mm shields, so check your shield size before purchasing.

## Compatibility & requirements

Compatible with many wearable and electric pumps that accept 24mm shields including various S9 and S12 models according to the product notes. These inserts will not fit shields of other diameters, so confirm your flange size before use.
