Description
Our 10.5mm cross-slit silicone dispensing valves are precision LSR (liquid silicone rubber) components engineered for accurate, leak-proof one-way dispensing in squeeze bottles — from condiments and sauces to cosmetics and personal-care liquids. Manufactured via high-accuracy LSR injection molding and micro-precision slit cutting, each valve delivers consistent flow control, rapid shut-off, and long life under repeated compression. Designed for easy integration into flip-top caps and closure systems, these valves combine food-grade safety, chemical resistance, and tight dimensional tolerances for dependable OEM packaging solutions.
