OEM Premier Liquid Toothpaste Dispensing Silicone Duckbill One Way Valves Factory

Overview

Our OEM Premier Liquid Toothpaste Dispensing Silicone Duckbill One-Way Valves are engineered for reliable, mess-free toothpaste and oral-care dispensing across squeeze tubes, pump closures, and flip-top caps. Manufactured from high-grade LSR (liquid silicone rubber) formulated for consumer health products, the single-piece duckbill geometry provides positive one-way flow, prevents backflow and drips, and resists clogging from viscous, particulate-filled pastes. Produced with precision LSR injection molding and cleanroom assembly, these valves are fully customizable in size, hardness, and actuation force to match a wide range of toothpaste viscosities and package interfaces—delivering consistent dosing, superior sealing, and long service life for OEMs and contract packagers.

Basic Information

Key Benefits

• Leak-proof, No-Drip Performance — Duckbill lip closure provides positive sealing after each squeeze to eliminate waste and countertop mess.
• Optimized for Paste Viscosity — Valve geometry and opening force are tuned to ensure smooth dosing for thick toothpastes, gels, and abrasive-containing formulas.
• One-Piece, Easy Assembly — Integrated design fits common flip caps and pump closures, reducing assembly time and leak points.
• Durable & Chemical-Resistant — LSR construction resists peroxide, fluoride, surfactants, and repeated compression cycles for long service life.

Quality Assurance

We apply strict QA protocols to ensure each valve meets performance and safety requirements: raw material certificates (FDA/LFGB/ROHS) verification, Shore A hardness testing, dimensional control via CMM and optical projectors, and functional tests including opening-force calibration, leak-proof/ backflow validation, and repetitive actuation fatigue testing. Environmental testing (thermal cycling, UV and chemical resistance) verifies long-term reliability. All production is traceable by lot and undergoes final inspection in a controlled environment to guarantee consistent OEM quality.

Factory Capabilities

Our tooling and production combine precision CNC moldmaking, mirror EDM, and automated LSR injection molding with cleanroom assembly to deliver high-accuracy duckbill valves at scale. We offer turnkey services from DFM and rapid prototyping to high-volume manufacture, supported by automated inspection (3D projectors, leak testers, durometers) and customizable packaging — enabling reliable, ready-to-implement valve solutions for toothpaste OEMs and contract packagers.
