We have tested our ComfortFit Flanges only with Lansinoh pumps, so we cannot guarantee compatibility or optimal performance with competitor's pumps. We hope this provides some clarity. **Q: Do these flanges fit the standard flange body, or do you have to buy a new set?** A: Mine do not fit into the pump. I got the 36mm flange and they are slightly smaller on the connecting end so they just fall right out. Wasted time and money... **Q: What size breast do these fit ?** A: I have double d and they fit but its more the nipple that needs to fit not the breast. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect fit *by M***N on July 30, 2026* Jusy what I needed, no complaints. ### ⭐⭐⭐⭐⭐ So far so good! *by D***E on March 20, 2026* My insurance came with the 21 and 24mm and both were too small and painful for me, the 28 one fits perfect, it makes pumping much easier, I love how the edges soft silicone so it doesn't hurt your skin. These are so much more comfortable than my old medela! ### ⭐⭐⭐⭐⭐ Great product!!! *by T***E on April 13, 2026* The product provides an excellent fit and remains secure even during vigorous movement. I felt compelled to upload this video because other demonstrations I encountered appeared to misrepresent the product's functionality, seemingly attempting to portray it negatively. Consequently, I decided to acquire and evaluate the product myself as my wife was between purchasing an 21mm insert as the 24mm Lansinoh flange was too big and the video reviews didn't seem honest. ## Frequently Bought Together - Lansinoh ComfortFit Breast Pump Flanges, Size 21mm, 2 Count - Lansinoh Manual Breast Pump, Hand Pump with Comfortable Flange, Includes 5oz Baby Bottle with Slow Flow Nipple, Breastfeeding Essentials - Lansinoh Breastmilk Storage Breast Pump Bottles, 4 Count --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/323058632-lansinoh-breast-pump-flanges-21mm-2-count](https://www.desertcart.vn/products/323058632-lansinoh-breast-pump-flanges-21mm-2-count) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-09-10*
