Overview
Our OEM Food-Grade Silicone Rubber Miniature Cross-Slit Valves for Sauce & Honey Squeeze Bottles are engineered for reliable, mess-free one-way dispensing in condiment applications. Made from 100% food-grade LSR or silicone, these miniature cross-slit valves combine ultra-low opening pressure with fast reseal and excellent chemical resistance—ideal for viscous liquids like ketchup, honey, and sauces. Manufactured via high-precision LSR injection molding and micro die-cutting, the valves are fully customizable in diameter, slit geometry, hardness and color to match your bottle cap systems and flow-rate targets.

Key Benefits
- Leak-Proof One-Way Flow — Cross-slit geometry provides controlled dispensing with no drips or backflow.
- Optimized for Viscous Fluids — Tunable slit size and hardness for ketchup, honey, sauces and concentrates.
- Food-Safe & Durable — 100% food-grade LSR with high chemical and temperature resistance.
- OEM-Ready Customization — Diameter, slit pattern, color, and branding options to integrate with your caps and closures.
Quality Assurance
Every valve batch undergoes strict QA: raw-material verification (FDA/LFGB), dimensional control with 3D optical measurement, slit geometry inspection, leak-proof and flow-rate testing under variable pressures, Shore A hardness checks, and long-cycle actuation testing to validate reseal life. Thermal and chemical resistance tests confirm reliability across –40°C to +230°C. All production runs are traceable and inspected in accordance with ISO 9001 protocols.

Factory Capabilities
Our facility combines CNC tooling, Mirror EDM and precision wire cutting to produce micro-accuracy valve tooling, supported by automated LSR injection molding and compression presses for consistent production. We perform micro die-cutting and cleanroom assembly for contamination-sensitive orders, and use 3D projectors, sealing testers, durometers, and elasticity gauges for inspection. With ISO 9001 systems, AutoDryers and precision die-cut lines, we deliver repeatable, high-quality miniature cross-slit valves optimized for sauce and honey squeeze bottle applications.
