Breast pump flange

Start with your nipple diameter and breast tissue, then pick a flange size that fits around the nipple with minimal pressure and no pinching. In this catalog, you’ll find common sizes and BPA-free materials like silicone or multi-material options to suit comfort and safety. Also consider your pump type—manual, single-electric, or double-electric—to ensure the flange connects securely to your device.

A correct flange diameter and funnel depth are the most complex attributes because they directly influence suction efficiency and comfort. If the flange is too wide or too deep, you may pinch or lose suction, while a too-narrow flange can cause rubbing and reduced milk flow. Material and shape also matter: choose BPA-free silicone or other safe materials and prefer a design that matches your anatomy and pump type for better comfort and output.

Beginners typically benefit from a straightforward flange with a comfortable fit and easy cleaning, paired with a reliable manual or entry-level electric pump. Experienced users who pump often should opt for wearable electric designs that offer multiple flange sizes (for example, a 24mm option) to fine-tune fit and maximize efficiency when pumping at home or on the move.

Always wash the flange and any connected parts after each use with warm water and mild soap; avoid harsh cleaners. Inspect for cracks or discoloration and replace if damaged. Mount the flange so the nipple sits comfortably in the center of the tunnel, and use compatible nipple protectors or shields if your kit includes them to prevent rubbing and protect skin.

Look for items labeled as breast shields or flange accessories, especially those noting size or BPA-free materials. For example, some entries include a 24mm flange on a wearable electric setup, and there are BPA-free nipple protectors and shields designed to fit multiple pumps—great options when you want a spare or a different size for comfort and efficiency.
