Description:
Our OEM One Way Silicone Valves are engineered from 100% FDA- and LFGB-compliant, food-grade liquid silicone rubber (LSR) to deliver exceptional leak-proof, hygienic, and precise dispensing performance. Manufactured through advanced LSR injection molding and precision micro-slit cutting, these valves ensure smooth, controlled flow of liquids while preventing backflow, contamination, or leakage. Ideal for dispensing closures in food & beverage, cosmetics, household cleaning, and medical packaging, they combine superior elasticity, chemical resistance, and long-term durability. As a trusted silicone manufacturing partner, we provide fully customized OEM solutions—including size, opening force, slit geometry, and branding integration—tailored to your unique dispensing requirements.
