NUK replacement nipples are made from silicone. Product listings consistently list the material as “Silicone.”
Listings show multiple flow levels. Commonly listed options include Level 1 — Slow Flow, Level 2 — Medium Flow, and Level 4 — Fast Flow. Availability may vary by specific product listing.
Age recommendations vary by product. Example listings show ranges such as “0–12 months” and “6 months and up,” reflecting nipples intended for newborns through older infants depending on the model.
Most NUK replacement nipple packs shown in the listings are sold as 2-count packs (Package Quantity: 2).
Descriptions emphasize a super-soft, skin-like silicone nipple that molds to the baby’s palate, a wide shape with a gradual slope, and a wide, deep latch designed to mimic breastfeeding and support a natural feeding position.
Many listings state the nipples are BPA‑free. One listing notes compliance with ASTM standards, while others list no certifications. Certification and safety claims vary by product—check the individual product page or packaging for exact certification details.
