Description:
Our OEM Food Grade 13mm Cross Slit Silicone One Way Degassing Valves are designed to deliver precision-controlled dispensing and reliable venting performance for flip-top sauce bottle caps and similar packaging systems. Made from 100% BPA-free, FDA- and LFGB-compliant liquid silicone rubber (LSR), these valves are produced through precision LSR injection molding to ensure exact dimensions, high elasticity, and superior sealing performance. The innovative cross-slit geometry allows effortless one-way dispensing while preventing leakage, backflow, or contamination—making them ideal for sauces, condiments, dressings, and other liquid food applications. Engineered for consistent flow and durability, these valves operate smoothly under repeated use, helping brand owners enhance packaging convenience and consumer satisfaction.

Quality Assurance:
Quality assurance for our OEM silicone one-way degassing valves prioritizes compliance, precision, and long-term reliability. Raw silicone materials are stringently verified to be BPA-free and meet FDA and LFGB food-contact requirements. During production, valves undergo rigorous testing, including flow rate analysis, leak-proof and backflow resistance checks, and repeated cycle fatigue testing to ensure consistent dispensing performance. Dimensional accuracy is validated with CMM inspection, while Shore A hardness and tensile strength are measured to guarantee elasticity and durability. Manufactured in our ISO 9001 and IATF 16949 certified facility, all products undergo batch traceability, inline inspection, and final QC checks within a controlled cleanroom environment.
