## Description

Duckbill Valve and Silicone Diaphragm Compatible with S18 S21, Replace MomMed Mumgaroo Momcozy M1 Breast Pump Parts

Review: I recently purchased this replacement duck-valve for my breast pump and I am very pleased with how well it fit. It matched up perfectly with the original part in my unit, and installation was straightforward, I simply removed the old valve and popped this one in; there were no gaps or loose connections. Once installed, the performance was excellent. The suction was strong and consistent, just like it was when the pump was new. I did not notice any loss of pressure and no unusual noise or leakage around the valve. That reassured me that the fit was not only precise but also tight enough to maintain the pump’s function.
