Overview:
Our Custom Silicone One-Way Air Breathing Valves are engineered to deliver smooth, controlled airflow and superior acoustic isolation for next-generation gaming soundproof masks and wearable comfort devices. These valves ensure efficient exhalation while blocking reverse airflow, maintaining both breathability and sound insulation during extended gaming sessions or studio use. Manufactured from 100% medical- and food-grade liquid silicone rubber (LSR), the valves combine flexibility, long-term durability, and precise sealing performance. Using advanced LSR injection molding and precision die cutting, we achieve exact geometric control to ensure silent operation, consistent air passage, and ergonomic integration into complex mask assemblies.
