FAQs

A model-specific MomMed replacement component for S21, offered in the exact sizes or pack quantities shown in the product options.

It is designed for S21 pumps. Match both the model name and selected size or part before ordering; visually similar parts from another model may not seal correctly.

A stretched valve, warped diaphragm or poorly seated flange allows air to leak from the system. That can make suction feel weak, inconsistent or noisy even when the motor is working normally.

Separate the part after each use, wash it with warm water and mild dish soap, rinse thoroughly and air-dry completely on a clean surface.

Inspect it after every wash. Replace silicone parts when they tear, curl, stretch, turn sticky or no longer seal flat; replace a cup or shield if it cracks, scratches deeply or warps.

Yes, but if output differs between sides, compare valve and diaphragm condition first. Replacing heavily worn parts on both sides at the same time can make suction feel more consistent.
