All You Need In One Place

Pumping Mamas Must Have: 4pcs Duckbill Valve and 2pcs Silicone Diaphragm Included

For moms using S18/S19/S21/S23 wearable breast pumps, our diaphragm and duckbill valve accessories are perfect solutions. Designed to replace parts every 4-12 weeks, these attachments maintain optimal suction and ensure your breast pump performs at its best.

No Backflow, Non-Leaking

The silicone diaphragm keeps your breast pump at a strong suction level, preventing the milk collector from leaking. The duckbill valve is specifically designed to prevent backflow of breast milk. These accessories are ideal for moms using a wearable breast pump.

Food Grade Silicone, BPA Free

All parts are made of food-grade silicone and are BPA free. They have passed BPA-free tests (CTB230320010CX) from CTB and US FDA tests (CTB230320009CX). Our parts are soft, safe, and odorless, ensuring the health and safety of both mom and baby.

Fits Perfectly with Different Breast Pumps

These replacement parts fit S21, Gekoja, TSRETE S21, MISSAA S18, Zooawa, Mumeasy, and Mumgaroo Wearable Breast Pumps. Not original pump parts, but they are compatible. If unsure about compatibility, send us photos of your breast pump, and we'll reply within 24 hours.

Easy Cleaning

After each use, these duckbill valves and silicone diaphragms can be sanitized using water steam, boiling water, or microwave-steam bags. For best results, use water heated to around 100°C (212°F).

Ideal Gift for Yourself and Loved Ones

Purchase our duckbill valve and silicone diaphragm replacement as an easy and comfortable gift bundle for yourself, your wife, girlfriends, and even colleagues. It simplifies their lactation periods.

Replacement Guidance

To keep your baby safe, replace breast pump parts every 4-12 weeks or sooner if they become deformed or yellowed after long-term use.
