breast pump parts

Common materials include silicone, polypropylene and other plastics (often labeled “Plastic” or “Polyethylene”), and ABS (Acrylonitrile Butadiene Styrene).

Listings typically use one of two approaches: broad compatibility claims (e.g., “Most Breast Pumps” or “universal”) or an explicit list of compatible pump models by name. Check product descriptions and images for model names or connector details to confirm a fit.

Common components in replacement sets include tubing, breast flanges/shields, backflow protectors or valves/membranes, and collection bottles or cups. Some listings bundle all these items for single- or double-pumping use.

Protective features include backflow protectors and valves, plus closed‑system tubing designs. These elements are described as preventing milk or contaminants from reaching the pump motor or tubing.

Capacities vary by product. Example listings include “1 oz / 30 mL per cup,” “each cup holds up to 5 oz,” and “each cup holds 250 mL.”

Package quantities range from single items to multi-packs. Example quantities shown in listings include 1, 2, 3, and 6 pieces.
