Description keyboard_arrow_down
add remove

The duckbill valve is the small silicone part that creates the vacuum and directs the milk flow in the right direction. It's what makes pumping work, and it's also the first part to check when suction weakens.

Made from soft, food-grade silicone, BPA-free. It's designed to wear out, which is normal, it's its job. Anticipate replacement rather than suffering a drop in efficiency.

Frequently Asked Questions

How to tell if my valve is worn out? keyboard_arrow_down
add remove

Signs: unexplained loss of suction power, deformed valve, visible cracks, or a valve that no longer stays in place in the connector.

When in doubt, replace it; it's often the culprit when the draw loses effectiveness.

How to clean the valves? keyboard_arrow_down
add remove

Wash with hot soapy water after each pumping session, or steam sterilize. Do not use sharp utensils to clean, as this would damage the silicone and render the valve unusable.

Should you spay/neuter them? keyboard_arrow_down
add remove

Yes, before first use.

Afterward, washing them with hot water and mild soap after each use is sufficient.

You can sterilize them occasionally if you wish.

    These two small breast shields saved my breastfeeding journey and, most importantly, allowed me to transition to hands-free pumping. Being braless and having my hands free during pumping completely changed the game. Not to mention the unparalleled comfort compared to other types of breast shields. With LUPA, I've even dozed off during a pumping session without worrying about them coming off.

    Since I returned to work, the old models were restrictive on a daily basis, especially when getting dressed with the appropriate bras. With your product, everything is simpler: comfortable, practical, and easy to integrate into my routine. I use it everywhere and very often, which proves how much it makes my life easier. Thank you for this quality!

    Initially, I had a lot of trouble getting them to stay put, but with the right size, it really works.

    The silicone is very comfortable and I have both hands free while pumping. Drainage is quick and efficient, I recommend these flanges to all pumping mothers.

    As you know, my pumping journey has been quite intense (we're nearing the end now) and the Lupas really helped make it easier. The simple fact of not having to wear a pumping bra, especially for night sessions, makes a huge difference. And the comfort! Thank you for creating these gems and for allowing me to benefit from them on the other side of the world 💜

    I can only recommend the LUPA 🐺💜

    Finally hands-free, more comfortable and truly optimized pumping sessions! They clearly helped me to continue after returning to work. Once you get the hang of it, it's a real joy. Big plus: they also adapt to manual and hospital-grade breast pumps.

    I wouldn't go back for anything in the world. LUPA is incredibly effective: comfortable, practical, and beautiful to boot. They have completely changed my daily life and made pumping so much simpler and more pleasant. You can tell they've been thoughtfully designed. Thank you for imagining and creating these true little gems 🐺💜

    I received my flange inserts 2 days ago and I'm already won over! I pump almost double in half the time, without massages or compressions like before. Finally, comfortable, hands-free pumping, even at work behind my computer 😊 Honestly, I should have bought them sooner... Thank you for this incredible invention 😍

    One word: magical ✨

    I regret not having known about LUPA sooner! I hesitated for a long time before ordering, thinking it was mostly marketing... and yet, from the very first try, I pumped an extra 100 ml. A real gain in comfort and efficiency every day. I wholeheartedly recommend it 🐺💜

    These breast shields are a real revolution 🐺💜

    Super comfortable, easy to use, and above all, much more effective than anything I'd tried before. My pumping sessions have become much more pleasant, quicker, and so much less restrictive in my daily life. Honestly, I couldn't do without them now!
