Baby Bottle Nipples in 50 60 and 73 Caliber Series
The Silicone Baby Feeding Set comes in six configurations, from a 4-piece starter to an 8-piece set — all in one matched five-color system, at a low 500-piece MOQ per configuration.
50 Caliber Baby Bottle Nipples
The 50 caliber range includes a conventional baby bottle nipple, a flatter drinking-spout structure and a raised outlet for straw connection. Matching straight and weighted straw components are also available. This gives you several feeding structures within the smaller caliber category, whether you need a standalone replacement nipple or a straw-compatible product.
60 Caliber Baby Bottle Nipples
The 60 caliber range provides several rounded silicone baby bottle nipples with different upper profiles, including conventional nipple and straight-outlet designs. Compatible long-straw and weighted-straw components expand the range beyond standalone nipples, allowing you to source both standard feeding and straw-compatible products within the 60 caliber category.
73 Caliber Baby Bottle Nipples
The 73 caliber range combines wider-flange baby nipples with rounded nipple, tapered spout and straight-outlet profiles. Assembled nipple-and-straw combinations are also available. For wider-neck bottle projects, this series gives you both standalone replacement nipples and complete straw-compatible structures without limiting the range to one nipple shape.
Add Replacement Baby Bottle Nipples to Your Existing Bottle Line
Offer standalone replacement nipples for changing feeding needs without requiring customers to purchase another complete bottle.
Sell the Nipple as a Separate Product
Many customers want to retain the bottle body and collar while replacing only the nipple. Adding standalone baby bottle nipples allows you to meet this demand with a lower replacement cost than purchasing another complete bottle. It also extends the commercial life of your existing bottle range by adding a continued accessory sales opportunity.
Cover Changing Feeding Stage Requirements
As feeding volume and sucking ability change, the same bottle may require nipples with different flow characteristics. You can develop silicone baby bottle nipples with different milk-opening shapes, opening sizes or nipple structures for each planned stage, allowing your bottle range to remain relevant as feeding requirements change.
Expand the Product Line without Replacing the Bottle Platform
When the nipple flange and sealing structure remain compatible with your existing assembly, new baby nipples can be developed around the current bottle body and collar. You can add replacement and flow-specific products without developing another complete bottle, reducing the additional investment required to expand your product range.
Expand Your Bottle Range with Compatible Nipples
Share your bottle structure, nipple dimensions and planned flow stages. We can help you develop standalone silicone nipples that match your existing bottle range.
Customize Silicone Baby Bottle Nipples for Existing Bottles
Combine an established bottle-side interface with different upper nipple structures.
Match the Nipple Base to Your Existing Assembly
The base of a new baby bottle nipple follows the flange and sealing profile of your original nipple. We match the relevant dimensions according to your sample or drawing, allowing the new nipple to maintain the required assembly relationship with your existing bottle neck and threaded collar.
Build Different Upper Forms on the Same Base
Once the lower interface is confirmed, the upper silicone structure can use a rounded nipple, flatter drinking spout or tubular straw connection. This gives you multiple baby bottle nipples with distinct appearances and feeding structures for the same bottle platform.
Concentrate Product Changes in the Silicone Nipple
The nipple direction, upper profile, wall structure and outlet configuration can be adjusted within the silicone nipple while the bottle neck and threaded collar retain their existing designs. This concentrates development on the component that creates the required product differences and keeps the current bottle-component system in use.
Develop Replacement Baby Bottle Nipples from Samples
Use one complete bottle sample to establish both the nipple design and assembly conditions.
Start from the Complete Original Bottle
You provide one complete original bottle sample at the beginning of the project, including the bottle body, threaded collar and nipple. We use the assembled product to identify the actual interface, nipple compression and installed position. This gives your replacement baby bottle nipple a development reference based on the complete product it must fit.
Correct Sample Deformation before Establishing Dimensions
We inspect the original nipple for flange compression, body stretching, silicone ageing and outlet wear before establishing the product dimensions. These conditions are compared with the assembled position inside the original bottle. This helps us restore a more reliable structure and reduces repeated sampling caused by transferring deformation from a used nipple into the new mold.
Convert Your Required Changes into Development Targets
You confirm the nipple profile, silicone hardness, straw connection and milk-opening structure required for the replacement product. We convert these requirements into measurable dimensions and material targets while retaining the confirmed bottle-side fit. This allows you to create clear functional or visual differences within your existing baby bottle nipple range.
Verify Every Prototype in the Original Assembly
We assemble every replacement nipple prototype with the original bottle and threaded collar to check flange compression, sealing contact, leakage and assembled flow. These are required validation steps before sample approval. You receive a prototype result evaluated as part of the complete bottle system, providing a dependable basis for tooling confirmation and mass production.
Develop Baby Bottle Nipples from Your Original Sample
Send us the complete bottle body, threaded collar and nipple together with your required changes. We will evaluate the original assembly and define the prototype development targets.

Use one complete bottle sample to establish both the nipple design and assembly conditions.
| Parameter | What You Confirm | Effect on Your Product |
|---|---|---|
| Silicone Hardness | Confirm the target Shore A hardness or use the approved original nipple as the reference. | Hardness affects nipple softness, deformation under suction and recovery after compression. |
| Tip and Sidewall Thickness | Confirm the required thickness distribution across the tip, sidewall and transition area. | Two nipples using the same silicone hardness can produce different flexibility and recovery through different wall structures. |
| Upper Nipple Profile | Select a rounded nipple, flatter drinking spout, straight outlet or another approved profile. | The upper profile defines the feeding structure and creates visible product differences within your bottle range. |
| Milk-Opening Structure | Confirm the opening type, size, position and quantity, including round holes, slits or cross-cuts. | The milk opening is a primary factor affecting flow and must be confirmed through prototype and assembled testing. |
| Air-Vent Design | Confirm the vent position, slit form and opening response required for the nipple structure. | The vent supports air replacement as milk leaves the bottle, affecting flow stability and leakage performance. |
| Straw Connection | Confirm the straw diameter, insertion depth and connection structure for straw-compatible nipples. | A defined connection keeps the straw positioned beneath the nipple and supports the intended liquid path. |
Verify Flow Differences before Finalizing Baby Bottle Nipples
Compare flow versions against an agreed reference before confirming your final product range.
Use Your Approved Nipple as the Flow Benchmark
You provide an approved nipple or define the expected direction for each flow version. We use this reference to establish the comparative target for new baby bottle nipples. This gives your team a concrete basis for reviewing samples and keeps development focused on the flow difference your product range actually requires.
Approve Flow Labels from the Comparison Results
Using the complete bottle sample already provided, we compare candidate nipples under the same agreed liquid, fill level, bottle position and test duration. The results show whether the output difference supports your intended product classification. You then approve the final version and corresponding flow label, while actual feeding performance remains influenced by liquid properties and use conditions.
Production Control for Silicone Baby Bottle Nipples
Control molding cutting and version separation around your approved nipple design.
Stabilize Thin-Wall Nipple Molding
Before the full production run, we stabilize the molding conditions around the approved nipple until the flange fills completely, the thin walls form correctly and the surface matches the sample. During production, flash, incomplete filling or visible deformation triggers process adjustment. This keeps your silicone baby bottle nipples within the confirmed molding result.
Maintain Fine Mold Cavities and Vent Paths
We keep the nipple cavities and fine vent paths clean during production because accumulated residue can affect the formation of thin tips and flange edges. Mold condition is reviewed when surface marks, incomplete filling or release changes appear. This helps your nipple retain the intended contour across the detailed areas of the mold.
Position Milk Openings with Dedicated Cutting Setups
Each milk-opening and air-vent design uses a dedicated positioning method and cutting setup. We locate the baby bottle nipple from its confirmed flange orientation, control the cutting depth and monitor tool condition during production. This keeps the opening in the intended position and supports the outlet structure approved during sample development.
Separate Different Flow Versions during Production
When your order contains several flow versions, we separate their work instructions, cutting setups and handling containers throughout production. Each version remains identified until packing. This gives you better control over nipples that look similar externally but use different opening structures, reducing the risk of mixed flow versions in one delivery.
Packaging Options for Your Baby Bottle Nipples
Choose packaging around your sales channel, product positioning and the number of nipples included in each retail or OEM pack.
Printed Paperboard Hang Box
A printed hang box gives you enough space to present your brand, nipple flow, size, material and compatible bottle range. We can adjust the internal holder for one or multiple baby bottle nipples, helping you build clearly differentiated packaging for retail shelves and online product listings.
rPET Carded Blister Pack
The clear rPET blister keeps the nipple visible while holding it in a defined position against the printed card. Different flow rates can use separate card colors and information layouts, allowing your distributors and retailers to distinguish silicone baby bottle nipples without opening the package.
Printed BOPP/CPP Retail Pouch
A printed BOPP/CPP pouch combines a clear brand surface with a reliable heat-sealed closure. Its compact structure reduces packaging volume and leaves room for flow, age and compatibility information, giving you a practical retail option for e-commerce, regional distribution and price-sensitive product lines.
Heat-Sealed CPE or PE Inner Pouch
For OEM supply, replacement nipples or products packed inside an outer box, we can seal each nipple or set in a CPE or PE pouch. The separate inner pack limits direct handling during sorting and packing while helping you organize different flow rates before bulk delivery.
