Description:
Our 33 mm No-Leak One Way Squeeze Bottle Valves are precision-engineered for clean, consistent ketchup and sauce dispensing. Manufactured from FDA- and LFGB-compliant, platinum-cured food-grade silicone, these valves are produced using liquid silicone rubber (LSR) injection molding and precision cross-slit cutting. The one-way check design ensures effortless squeeze-to-dispense action while preventing drips, leaks, and air backflow—delivering a superior consumer experience with every use. With excellent thermal stability (–40 °F to 450 °F), high elasticity, and long-term durability, these valves are ideal for ketchup, condiments, syrups, and other viscous liquids.
As an OEM manufacturer, we provide end-to-end customization—from slit geometry, hardness, and flow rate to diameter sizing and bottle cap integration—ensuring your packaging solution is fully optimized for brand performance and consumer convenience.
