Keep a spare ready for the next cup clean-up. This set includes 16 clear silicone replacement spouts, listed for compatible NUK Active and Learner cups with a 5 cm opening.
16 silicone spoutsClear finishReplacement parts; cup not included
NUK is mentioned only to identify stated compatibility. These are RBUGR replacement parts, not NUK-branded products.
The details
The listing identifies silicone construction, a two-line opening and an air valve. The stated fit is for selected NUK Active and Learner cups with a 5 cm opening. Compatibility is model-specific; compare the original part, cup and measurements before ordering.
Use & care
Follow the supplied cleaning instructions before first use and after each use. Inspect for damage and replace worn parts. Always check assembly and supervise use. Do not assume that a similar-looking cup has the same fit.
Delivery & returns
Delivery dates, charges and eligibility for returns depend on the selected offer and your destination. Check them during checkout, and use the order account for after-purchase support.

A closer look / 16 pack
Match your cup before building a spare supply
A 16-piece spare-parts plan
Sixteen pieces offer a larger spare supply when you have several confirmed-compatible cups. Keep parts grouped by cup model and avoid choosing quantity before you have resolved compatibility. Individual review text for this sixteen-piece listing was not available in our captured source.
Compare the exact cup model, the original part and the stated dimensions. The listing identifies selected NUK Active and Learner cups with a 5 cm opening; this is not a universal compatibility claim. Choose a quantity only after resolving the fit.
Details worth checking
Keep model information with your spare parts. Follow the cup and replacement-part care instructions, inspect before use and replace damaged parts. Do not modify an opening or force a fit. Cup not included; NUK is named only for stated compatibility.
Read the related buying guidance ↗What the review evidence tells us
The six-piece listing has comments about successful fit and easy cleaning, as well as a report of leaking. That feedback cannot verify a different cup or the sixteen-piece listing. Inspect the complete assembly using the applicable instructions.
Editorial interpretation of the available source, not independent testing. Individual experiences vary. The sixteen-piece rating is separate from the six-piece review sample discussed above.
Keep the right spare easy to find
Store cleaned, fully dry parts by their matching cup model, with the relevant care instructions available. If your household uses more than one cup design, keep the groups separate. A positively identified spare is more useful than a mixed drawer of similar-looking parts.
