We offer a wide range of standard silicone valve designs, including cross-slit valves, duckbill valves, and umbrella-style valves, providing convenient options for different dispensing and flow control requirements. Our standard valve range includes 8mm, 9.8mm, 10.5mm, 13mm, and 16.5mm cross-slit silicone valves, as well as 12.5mm silicone duckbill valves, 33mm silicone NSF valves, and 84mm silicone fermentation lids. Made from high-quality silicone materials, our valve solutions provide reliable sealing, controlled fluid flow, and leak-proof performance. For applications with specific dimensional, flow rate, hardness, or sealing requirements, we can also develop customized silicone valve solutions based on your drawings or specifications.

38-400 Flip Top Cap with Silicone Valve | Leak-Proof Honey Bottle Cap

38-400 flip top cap, also known as a plastic honey bottle cap, features a 40mm outer diameter and an integrated silicone dispensing valve. Designed for squeeze bottles, the valve provides reliable sealing, controlled dispensing, and a clean dispensing experience. The silicone valve helps prevent leakage when the bottle is stored upside down and provides a smooth, controlled flow when squeezed. The optimized slit design helps prevent split streams and reduces liquid residue around the bottle opening after dispensing, making it ideal for honey and other viscous food products. Made for food packaging applications, this flip top closure combines convenient one-hand operation with reliable leak-proof performance. Standard designs are available for fast sampling and production.
