The Difrax S-Bottle Valves 2 Pack is a set of replacement anti-colic valves for the Difrax S-baby bottle. Each valve sits inside the bottle's removable base and works as part of the feeding system to give a steady, regular flow of formula or breast milk during feeds. Because valves are a wear part — much like teats — keeping a spare pair on hand means you can swap them out on schedule and keep the bottle performing the way it should.
The valve carries Difrax's anti-colic design: it's shaped to manage the air that mixes with the milk as your baby feeds, which is the mechanism behind the "anti-colic" name. Made from soft, BPA-free silicone, it's designed to be gentle in daily use while integrating neatly into the base so the bottle keeps its usual sleek, easy-to-handle shape.
Compatibility
These valves are designed to fit all Difrax S-baby bottle sizes, so they suit your existing S-baby bottles without needing to match a specific volume. They're a Difrax-specific part, so they're intended for the S-baby bottle system rather than other bottle brands.
How to Use
- Before each feed, squeeze the valve several times to make sure the tiny air hole in the centre is open.
- Fit the valve into the removable base of the bottle as part of your usual assembly.
- Replace the valve routinely, just as you would the teat — Difrax recommends changing it every six weeks with daily use.
Caring for the valve
Regular replacement keeps the valve working as intended: an open air hole and an intact silicone valve are what allow it to maintain a consistent flow. Checking and squeezing it before each feed is a quick habit that helps you spot when a valve is due to be swapped out.
