Description:
Our Customized 9.8mm Snowflake Silicone Sealing Valves are precision-engineered using liquid silicone rubber (LSR) injection molding technology to deliver superior leak-proof performance for modern water bottles and hydration systems. Featuring a unique snowflake slit design, these one-way valves provide effortless flow control while preventing backflow, spills, and leakage—even during vigorous movement. Made from 100% FDA- and LFGB-compliant food-grade silicone, the valves are safe for prolonged contact with water and beverages, ensuring taste neutrality and long-lasting durability. With excellent resistance to temperature extremes, UV exposure, and repeated compression cycles, these valves maintain reliable performance in both hot and cold environments. As your trusted OEM partner, we provide end-to-end customization—including dimensions, slit geometry, hardness (Shore A), and branding—backed by scalable high-volume production to meet global market demands.

Quality Assurance:
Quality assurance for our OEM 9.8mm Snowflake Silicone Sealing Valves is built around ensuring consistent sealing integrity, safety, and full compliance with international food-contact standards. Every batch of raw silicone is thoroughly tested to confirm it is BPA-free and both FDA- and LFGB-compliant. Throughout production, we apply advanced testing protocols, including Shore A hardness measurement for elasticity, flow rate and leak-proof testing under simulated use conditions, and durability evaluations for both high- and low-temperature environments. Additional assessments include tensile strength and tear resistance analysis to verify long life cycles, along with dimensional inspections using CMM and optical systems to guarantee precise 9.8mm sizing. Each production batch is fully traceable and undergoes final QC checks in a cleanroom environment, ensuring every valve meets the highest standards of hygiene, safety, and performance.
