What’s inside

• Two 13mm flanges
• Two valves
• Two backflow protectors
• Two tubings

Interchangeability and use

These Maymom parts are designed to be interchangeable with Spectra pump components. You can pair with Spectra flange, backflow protector, valve, and tubing. The kit is intended for use with wide-mouth bottles only, offering a seamless mix-and-match experience for everyday pumping routines.

In real-life pumping sessions, the ability to swap between brands and bottle systems can help you maintain consistency without expanding your toolkit. The closed system design helps keep milk away from tubing, simplifying cleanup after sessions.

Care, safety, and quality

• All parts are BPA-free and can be cleaned with water, steam, or boiling water. Independent lab test reports are available for reference.
• Follow standard sanitation steps: wash, steam or boil, and air-dry before reassembling.
