The 10.5mm silicone dispensing valve is a precision-engineered component designed for refillable liquid-dispensing cleaning brushes, including dishwashing and toilet cleaning tools. With a 3 × 3 mm cross slit, it delivers reliable sealing and controlled dispensing, ensuring stable performance under frequent, everyday use.
As cleaning tools increasingly adopt integrated liquid reservoirs, the valve becomes critical for both leak prevention and smooth dispensing. Hopewell addresses these requirements by carefully optimizing slit structure, wall thickness, and material elasticity to achieve a balance between tight sealing and easy liquid release.
Manufactured from eco-friendly, platinum-cured liquid silicone rubber (LSR), the valve meets FDA and LFGB standards for safety and durability. Combined with high-precision liquid injection molding, it ensures consistent dimensions, stable mechanical properties, and long-term reliability across large production volumes.
The 3 × 3 mm cross slit is engineered to provide strong sealing, even when brushes are stored upright or hung for extended periods. At the same time, optimized slit geometry enables consistent liquid output without clogging, splitting, or irregular flow, ensuring a clean and controlled dispensing experience.
Cleaning brush applications present unique usability challenges, especially when dispensing thicker liquids or when the remaining liquid is low. By refining key structural parameters such as wall thickness and opening stroke, Hopewell’s valve allows users to dispense liquid more easily with reduced force, while still maintaining excellent sealing performance.
Compared with conventional designs, this valve offers improved efficiency and user experience, including reliable leak prevention, smoother dispensing of remaining liquid, reduced residue, and consistent performance over repeated use cycles. In addition, Hopewell provides full customization support, including slit design options, size adjustments for different viscosities, material hardness tuning, and engineering collaboration to accelerate product development.

Kitchen dishwashing brushes
Toilet cleaning brushes
Shoe cleaning brushes
Multi-purpose household scrub brushes
It is ideal for dispensing detergents, soaps, and other cleaning liquids with medium viscosity.
With extensive experience in silicone valve manufacturing, Hopewell supports global customers with high-performance dispensing solutions. Backed by in-house tooling, rapid prototyping, and stable high-volume production, we ensure strict quality control and consistent product performance. Our proven expertise in balancing sealing and dispensing has enabled us to successfully supply silicone valves to multiple domestic and international brands in the cleaning tools industry.
A 10.5mm silicone dispensing valve is mainly used in refillable cleaning tools such as dishwashing brushes, toilet brushes, and scrub brushes. It controls liquid flow while preventing leakage during storage and use.
The valve uses a precision cross slit design combined with high-elasticity LSR material. This allows the slit to remain tightly sealed when not in use and open only under applied pressure, ensuring reliable leak-proof performance.
Yes. The slit size, structure, and material hardness can be customized to suit different liquid viscosities, from light soaps to thicker cleaning solutions.
Yes. The valve is made from platinum-cured liquid silicone rubber (LSR), which complies with FDA and LFGB standards, making it safe, non-toxic, and environmentally friendly.
Yes. We provide samples for testing and validation to ensure the valve meets your performance requirements before proceeding to large-scale production.
