About this product

Product information from the supplier.

Our high-performance EPDM and Silicone rubber grommets are engineered to provide superior mechanical protection for wiring, cables, tubing, and piping. Specifically designed for demanding applications such as cable winches, automotive systems, and industrial machinery, these grommets eliminate friction and prevent wear caused by sharp edges of drilled or punched holes.

Leveraging advanced polymer technology, we offer a diverse range of materials including NBR, NR, EPDM, FKM, and Silicone to ensure optimal sealing, damping, and environmental resistance. Whether you require standard sizes or custom-engineered specifications based on your unique technical drawings, our products guarantee long-term durability in extreme temperature and pressure conditions.

Frequently Asked Questions

Q: How do I choose the right rubber material for my grommet?

Material choice depends on your environment. EPDM is best for weather/ozone resistance, NBR for oil resistance, and Silicone for high temperatures or food-grade requirements. If unsure, provide your application details and we will recommend the optimal polymer.

Q: Can you produce rubber grommets based on a hand-drawn sketch?

Yes, we accept drawings, sketches, or even detailed ideas of usage. Our engineering team will transform these into technical specifications and produce the real rubber grommets for you.

Q: What is the typical lead time for custom molded rubber parts?

For items in stock, delivery is 5-15 days. For items requiring new molding, it typically takes 25-35 days. If the mold already exists in our library, the time is reduced to 10-20 days.

Q: Do your rubber products meet international environmental standards?

Yes, our products are compliant with ROHS and ISO9001:2008. We use UL-approved rubber compounds to ensure safety and environmental compliance for global markets.

Q: What is the minimum order quantity (MOQ) for custom grommets?

Our standard MOQ is 200 pieces. However, we are open to discussing small orders depending on the complexity and material requirements of your project.

Q: What industries typically use your rubber sealing products?

Our products are widely used in automotive manufacturing, industrial machinery, medical devices, bathroom facilities, and household electrical appliances for sealing, damping, and protection.
