Rubber Gasket for Conical Pail Lid is a sealing strip installed inside the conical lid to improve the seal between the lid and the container, preventing leakage of paint, chemical liquids, and other media. It also blocks the intrusion of air, moisture, and contaminants, ensuring safety during transportation and storage. It is typically made of EVA, rubber, or silicone and is compatible with metal lids of various structures and sizes.

Features of Rubber Gasket
1. Excellent Sealing Performance
Developed specifically for paints, oils, and hazardous chemicals, it offers high sealing pressure accuracy, effectively preventing leakage caused by vibration during transportation and stacking, enhancing chemical packaging safety.
2. Precise Fit for Multiple Container Types
Compatible with various container types including conical, tinplate, straight-edged, and rolled-edge containers. Multiple models of EVA seals and rubber sealing rings are available.
3. High Chemical and Corrosion Resistance
The EVA material is resistant to weak acids and alkalis, greases, detergents, and most industrial chemicals. It does not swell, discolor, or dissolve, maintaining structural stability.
4. Excellent Aging Resistance
The antioxidant formula effectively prevents seal failure due to hardening and cracking, extending the seal life to 3-5 years or more.
5. Lightweight and Easy Assembly
It can be quickly snapped into the cap slot without special tools, improving filling line efficiency and reducing after-sales claims costs for customers.

FAQs for Rubber Gaskets
1. How do I install the rubber strip?
Installation is simple and tool-free. Just press the strip firmly into the dedicated channel (gasket groove) on the underside of the pail lid until it sits evenly and securely around the entire circumference.
2. How can I verify the seal is effective after… installation?
After closing the lid, perform a simple visual inspection to ensure the seal is evenly seated. For a reliable test, turn the sealed pail on its side or conduct a short-term storage test with a small amount of water to confirm there is no leakage.
3.What is the expected lifespan of the seal?
The lifespan depends on storage conditions and frequency of use. Made with an anti-aging formula, the strip is designed to maintain flexibility and sealing performance over a long period under normal conditions.
4.Can it handle temperature fluctuations?
Yes. The high-elasticity rubber material can withstand normal temperature variations encountered during storage and transportation, ensuring the seal remains effective.
5.How do I know which size to order?
Refer to the product specifications for the compatible pail models and sizes. You can also measure the length of the groove in your lid or contact our sales team for assistance.
