The 9.8mm silicone rubber valve is a precision-engineered dispensing component designed for inverted squeeze bottles used in concentrated cleaning products. With a 3.3 × 3.3 mm cross slit, it enables controlled, leak-proof dispensing while maintaining excellent rebound performance, making it ideal for modern no-flip-cap packaging.
As concentrated detergents continue to trend toward lightweight, inverted designs, higher demands are placed on valve sealing, flow control, and durability. This valve is specifically engineered to prevent leakage during storage and transportation, while delivering consistent output to reduce product waste and improve user experience.
Manufactured from platinum-cured liquid silicone rubber (LSR), the valve complies with FDA and LFGB food-grade standards. The material offers high tensile strength and elasticity, allowing the slit to close quickly after squeezing, effectively preventing dripping and keeping the bottle opening clean.
With a standard 9.8mm outer diameter, the valve fits a wide range of cap designs and is typically assembled with a 12.3mm plastic retainer ring. This standardized sizing ensures easy integration into existing packaging systems without requiring major design modifications.
Hopewell utilizes high-transparency, high-elasticity LSR materials to ensure long-term stability, wear resistance, and durability. Combined with precision LSR injection molding, the valve achieves uniform thickness and consistent dimensions, even in large-scale production.
To guarantee reliable performance, the production process includes fully automated slit cutting and 100% inspection of slit quality. This ensures smooth dispensing and consistent functionality across high-volume applications such as household cleaning products.
In addition, the valve is designed for seamless compatibility with automated cap assembly lines. Hopewell also offers flexible customization options, including various slit types (cross, star, snowflake), adjustable slit sizes for different viscosities, material hardness tuning, and color customization to match specific product requirements.

The 9.8mm silicone rubber valve features a 3.3 × 3.3 mm cross slit and optimized material hardness, making it ideal for controlled dispensing of medium- to high-viscosity liquids. Its design ensures smooth flow while maintaining excellent sealing performance, meeting the functional demands of modern inverted packaging.
This valve is widely used in household and industrial cleaning applications, including:
Concentrated dishwashing liquid
Concentrated laundry detergent
Toilet cleaners
Disinfectants
Engineered for performance, the valve provides a clean cut-off after each squeeze, effectively preventing dripping and residue buildup around the bottle opening. This not only improves hygiene but also enhances the overall user experience.
