Product Description
Oil Proof, Leak Proof and Spill Proof Custom NBR Rubber Valves
NBR rubber valve, also known as nitrile butadiene rubber valve, is a type of oil-resistant dispensing valve made from NBR elastomer material. Compared with silicone valves, which are widely used in food and beverage packaging, NBR rubber valves are designed for products containing oils, greases, or solvents that may cause silicone to swell or lose elasticity. NBR valves maintain reliable sealing and dispensing performance even when exposed to oil-based or chemical-based liquids, making them an ideal choice for non-food applications such as cosmetics, skincare, and industrial packaging.

Advantages of NBR Rubber Valves
1. Excellent Oil Resistance:
NBR material resists oils, lotions, and other hydrocarbon-based substances, ensuring the slit remains functional and leak-proof over time.
2. Good Elastic Recovery:
Provides consistent opening and closing force, ensuring smooth dispensing for a wide range of liquid viscosities.
3. Durable and Long-Lasting:
NBR valves exhibit strong mechanical strength and resistance to wear, suitable for frequent squeezing or pressing.
4. Customizable Design:
Valve dimensions, hardness, and slit structure can be customized to match specific bottle caps, flow rates, and product formulations.
5. Stable Performance in Assembly:
NBR rubber maintains dimensional accuracy and stability during high-speed automated assembly processes, reducing defect rates and downtime.
Applications of NBR Rubber Valves
NBR rubber valves are widely used in beauty, personal care, and household products where oil or solvent content is high, including:
● Cosmetic creams and foundations
● Essential oils and serums
● Lotions, shampoos, and conditioners
● Hair treatment products
● Industrial lubricants and cleaning agents
For these applications, silicone valves may lose sealing or slit elasticity after prolonged contact with oils, but NBR rubber valves remain intact and fully functional.

FAQ
1. What is an NBR rubber valve made of? NBR rubber valves are made from nitrile butadiene rubber (NBR), a synthetic elastomer known for its excellent resistance to oils, greases, and hydrocarbon-based liquids. This makes them ideal for applications where silicone valves may lose elasticity or sealing performance. |
2. What's the difference between NBR rubber valves and silicone valves? Silicone valves are typically used in food and beverage packaging because of their food-grade safety and flexibility. |
3. Are NBR rubber valves food grade? Generally, standard NBR rubber is not recommended for direct food contact due to its chemical composition. However, for non-food applications like beauty, personal care, and industrial packaging, NBR rubber valves are an excellent choice. If food-grade compliance is required, YEJIA can provide custom formulations or oil-resistant silicone alternatives. |
4. Can YEJIA customize the size and slit design of NBR rubber valves? Yes. YEJIA provides custom NBR rubber valve design based on your packaging requirements — including valve diameter, thickness, hardness (Shore A), and slit shape (cross slit, duckbill, or custom design). Our engineering team evaluates structure feasibility and provides prototype samples before mass production. |
5. How does YEJIA ensure the quality and consistency of NBR rubber valves? YEJIA controls the entire production process in-house — from mold design and LSR molding to automated punching and AOI inspection. Every NBR valve is tested for dimension accuracy, sealing performance, and elasticity, ensuring perfect fit and reliable dispensing performance during automated assembly. |
6. What industries use NBR rubber valves? NBR rubber valves are widely used in: Beauty and skincare products (cream, lotion, foundation) Personal care packaging (shampoo, conditioner, serum) Industrial and automotive packaging (lubricants, cleaning agents) They are suitable for any product where oil resistance and stable dispensing are required. |
7. What's the MOQ for custom NBR rubber valves? The minimum order quantity (MOQ) typically starts from 50,000 pieces, depending on the design and application. YEJIA provides prototype testing samples before mass production to ensure performance and compatibility with your packaging system |
8. Can YEJIA provide both silicone and NBR rubber valves? Yes. YEJIA specializes in both silicone rubber valves (for food-grade applications) and NBR rubber valves (for oil-based or cosmetic products). Our engineering team can recommend the most suitable material based on your formula and packaging requirements |
