Restore Suction & Prevent Leaks: The Universal Replacement Solution

Keep your wearable pump running like new with the GOCROWEEN Universal Duckbill Valve & Diaphragm Set. Specifically engineered to fit the most popular wearable pumps on the market, these parts are the key to maintaining strong suction and a hygienic, closed-system pumping experience.

The precision-molded duckbill valve ensures milk flows only one way—into your container—preventing messy back-flow and protecting your expensive pump motor from moisture and damage.

Why These Replacement Parts are Essential:

Massive Compatibility: Fully compatible with Momcozy (S9, S10, S12), TSRETE, Luxlady, HAUTURE, Paruu, and almost all standard S9/S10/S12-style wearable pumps.

Anti-Backflow Protection: The transparent silicone diaphragm creates a total barrier between your milk and the pump motor, ensuring every session is 100% hygienic.

Hospital-Grade Suction: Don't let a worn-out valve decrease your output. Replacing these parts regularly restores the vacuum power you need for an efficient let-down.

100% Food-Grade Silicone: Soft, BPA-free, and odorless. Safe for your baby and gentle enough for daily sterilization.

Heat-Resistant & Easy to Sanitize: Simply clean with warm soapy water or sanitize using steam, boiling water, or microwave steam bags.
