Product Introduction
When it comes to wire protection and hole sealing in outdoor environments, EPDM (Ethylene Propylene Diene Monomer) is the industry gold standard. Our custom-molded EPDM grommets are engineered to provide a durable barrier against the elements, preventing edge-wear on cables while ensuring long-term sealing integrity.
Designed for industries ranging from automotive and HVAC to renewable energy, our grommets are 100% customizable to meet your specific Shore A hardness, color-coding, and branding requirements.


Why EPDM?
EPDM is selected for grommets primarily for its exceptional stability in "open-air" environments where other rubbers might crack or degrade.
Core Material Specifications:
-
Weathering and UV Resistance: Exceptional. Does not crack or become brittle under prolonged sunlight exposure.
-
Ozone Resistance: Superior. Ideal for use near high-voltage equipment or urban pollution.
-
Thermal Stability: Maintains flexibility and sealing force across a wide temperature spectrum.
-
Chemical Compatibility: Excellent resistance to water, steam, aging, and polar solvents (ketones, alcohols).
Our Core Customization Capabilities
-
Specific Durometer (Hardness): We offer a precise range from 40 Shore A to 90 Shore A. Whether you need a soft, compressible seal or a hard, wear-resistant bushing, we verify the hardness of every batch.
-
Pantone & RAL Color Matching: We provide full-spectrum color customization. By using Pantone or RAL codes, we ensure your parts match your brand’s identity or meet industry-standard color-coding requirements.
-
OEM Logo Branding: Enhance your product's professional appearance with custom branding. Options include molded-in logos for permanent identification or high-precision laser marking for serial numbers and logos.
-
Custom Compounding: We can modify standard rubber formulas to include specific properties such as flame retardancy, conductivity, or enhanced UV protection.
-
Bespoke Packaging: From individual poly-bagging to custom-labeled boxes and retail-ready kits, we provide packaging solutions that streamline your assembly line or sales process.

FAQ
Q1: Is EPDM better than Silicone for outdoor grommets?
A: EPDM is generally more cost-effective and offers better abrasion resistance than Silicone, while providing similar levels of weather and ozone resistance, making it the superior choice for industrial wire protection.
Q2: Can EPDM grommets be used in contact with oil or gasoline?
A: No. EPDM is not recommended for petroleum-based fluids. If your application involves oil contact, we recommend our NBR or FKM custom components.
