Performance and compatibility

These components are engineered to maintain suction and form an air-tight seal, closely mirroring the performance of original parts. The set includes a range of flange sizes 15, 17, 19, 21, 24, 27, and 30 mm to suit different preferences. The backflow protector integrates with tubing to preserve suction across pumping cycles while remaining a closed system that protects your equipment.

Practical features for daily use

• Longer tubing for easier handling while pumping
• Leak-proof bottles with sealing discs and screw rings; compatible with standard nipples
• Wide temperature tolerance for fridge storage and safe warming

Care, safety, and guidance

All parts are BPA free and comply with FDA food contact regulations. Independent lab testing supports these claims. The bottles and components are dishwasher safe and can be cleaned via steam, boiling water, or microwave steam bags, helping you fit cleaning into busy days.

Flanges feature smooth angles for comfortable positioning, and the tunnel measures at least 32 mm to accommodate a range of nipple shapes.
