Diaphragms (also known as backflow protectors) keep milk and air from flowing back up the tubing. They prevent milk from getting into the breast pump motor and also keep your tubing as clean as possible.

Replace your silicone diaphragm every 8-9 weeks. It's crucial to replace it frequently especially if you use your pump multiple times per day.

Julian ★★★★★

Swapped out my old ones because milk was creeping up the tubing and these fit perfectly, sealing tight so the motor stays dry. The two-pack is handy since I can rotate them on wash days.

Isabella ★★★★★

Finally, no more milk sneaking into the tubing—the backflow protection works exactly as it should, and my pump motor stays dry even during heavy sessions. The pack of two is a lifesaver since I can swap one out while the other dries.

Brian S. ★★★★★

These are a perfect fit for my pump and do exactly what they’re supposed to. Since I switched them out, I haven’t had a single drop of milk back up into the tubing, and the whole setup stays noticeably cleaner after each session.
