Momcozy Flange M5 / M6 / M9 17 mm, Silicone Reducer Inserts for Funnels, Set of 4 pcs. (AS253-NA02NB-A)

Silicone reducing inserts for Momcozy Flange Insert M5 / M6 / M9 17 mm
Momcozy Flange Insert silicone reducing inserts are replaceable accessories for electric breast pumps, designed to adapt the flange diameter to the user’s individual anatomy. The product reduces the internal size of the flange tunnel to a diameter of 17 mm, which helps keep the nipple correctly positioned during milk expression. The inserts are universal accessories compatible with the cordless Momcozy M5, Momcozy M5 Smart, Momcozy M6 and Momcozy M9 breast pump models. Regular replacement of consumable parts is crucial for maintaining the device’s factory performance and suction power.

Material safety and Silicone construction
The inserts are made of soft and flexible food-grade Silicone, which fits securely against the walls of the plastic flange. This type of material is highly chemically neutral and free from harmful substances such as BPA. Properly shaped edges help reduce the risk of leaks and loss of suction power during operation of the pumping unit. These components are universal accessories intended for both Momcozy M5 and Momcozy M5 Smart models, as well as devices from the Momcozy M6 and Momcozy M9 series.

Maintaining stable vacuum and parts replacement schedule
Gradual wear of flexible consumable components is the main cause of a drop in proper vacuum in electric breast pumps. Stretching, abrasion or loss of the silicone’s original elasticity requires periodic replacement of parts to restore the pump’s correct operating parameters. According to the manufacturer’s technical guidelines, components such as the Diaphragm and Duck Valves should be replaced every 3 months. In turn, Flange Shields and Backflow Linker require replacement every 6 months.

Practical pack of four and heat sterilisation
The package contains 4 inserts in 17 mm size, providing a reserve of consumable materials and making it easier to rotate components during daily use. The Silicone material structure is resistant to high temperatures up to 212°F (100°C), allowing steam sterilisation and boiling in water for 3 minutes. Regular replacement of the inserts supports proper hygiene by limiting the build-up of milk fat residue in the nooks and crannies of the flanges.
