How to Choose the Right Connector

Picking the right connector is about matching shield size, bottle type, and how you plan to pump.

  1. Confirm Shield Size: Measure the inner diameter of your pump shield, wide-mouth connectors generally fit 13 to 32 mm shields.
  2. Check Bottle Compatibility: Use only wide-mouth bottles specified as compatible with your connector to avoid leaks and fit issues.
  3. Think Handsfree Use: If you plan to use a handsfree pump bra, choose the low-profile connector and test fit before long sessions.
  4. Keep Spares Handy: Connectors are small and easy to misplace, buying a spare pair avoids interruptions in pumping.
  5. Follow Cleaning Guidance: Wash top-rack in the dishwasher or steam sterilize as recommended, inspect parts for wear before each use.
Frequently Asked Questions
Does the connector work alone?

No, the connector is a spare part only. You must attach a compatible pump shield to create the flange needed for pumping.

Which shields and bottles will fit?

This connector is intended for wide-mouth shields that fall in the 13 to 32 mm range and for compatible wide-mouth bottles. Verify your shield and bottle specs before buying, as it will not fit every wide-mouth bottle.

How should I clean and sterilize these parts?

They are top-rack dishwasher safe and steam sterilizer safe. Rinse after use, wash according to your pump instructions, and inspect parts for cracks or damage before each use.

Are these original pump parts?

These are manufacturer spare connectors, not original parts from every pump maker. They are designed to match wide-mouth shields in the stated size range.

What are your shipping and return policies?

We ship from a US warehouse, offer free US shipping on orders over $100, and accept returns within 30 days. If you need help, our human customer support team is available.
