Description:
Our OEM No-Drip Silicone One Way Valves are precision-engineered using advanced LSR (Liquid Silicone Rubber) injection molding to deliver superior flow control and mess-free dispensing for ketchup, sauces, condiments, and other liquid food applications. Designed with a cross-slit configuration, these self-sealing valves ensure consistent, controlled dispensing while automatically preventing backflow, leaks, and drips. Manufactured from 100% BPA-free, FDA- and LFGB-compliant food-grade silicone, the valves combine outstanding elasticity with excellent tear resistance, ensuring long-lasting performance even under repetitive use. Temperature-resistant from –40 °F to 450 °F and fully dishwasher-safe, these valves are ideal for high-demand food packaging and dispensing systems. As your trusted OEM partner, we provide custom slit patterns, valve geometries, hardness grades, and branding options tailored to your specific application.

Quality Assurance:
Quality assurance for OEM silicone one-way valves focuses on precision, hygiene, and consistent dispensing performance. Raw materials are rigorously tested to confirm they are BPA-free and fully compliant with FDA and LFGB food-contact standards. During production, advanced inspection tools—including 3D optical projectors, slit uniformity testers, Shore A durometers, and high-cycle fatigue testers—are used to verify sealing performance, elasticity, and durability under repeated compression. Batch traceability and cleanroom-controlled final QC checks ensure every valve meets stringent safety and hygiene requirements. Our facility is ISO 9001 and IATF 16949 certified, guaranteeing world-class quality across every production run.
