Non-standard equipment requires custom rubber parts because standard parts cannot fit complex offset shapes. Custom Silicone Parts use offset dual-groove designs to provide two sealing barriers, preventing moisture penetration and filling assembly gaps to achieve IP68 ratings.
Water leaks almost stopped my development project completely. If you are searching for solutions to seal offset interfaces, I invite you to read further. I will share my hands-on engineering experience.
Offset structures on non-standard charging guns caused regular seals to deform excessively. Tiny gaps allowed water and dust to enter internal circuits. My entire testing unit was ruined. I felt immense pressure. So, I designed offset dual-groove silicone rings.
Offset dual-groove silicone rings distribute compression stress through groove channels. Dual annular grooves increase rubber rebound space. This design provides double-layer sealing under pressure, eliminating tiny gaps in offset interfaces completely.
I redesigned my solution completely. I developed this offset dual-groove silicone ring. Its two annular grooves provide even secondary rebound when compressed. The first groove blocks water, while the second groove isolates fine dust. This structure improves recovery after compression deformation significantly.
I compiled the following data table to compare structural performance clearly:
| Structure Type | Sealing Barriers | Compression Rebound | Offset Fit Quality | Target Application |
|---|---|---|---|---|
| Single Flat Ring | 1 Barrier | 60% | Poor | Standard Round Holes |
| Symmetric Dual Groove | 2 Barriers | 75% | Fair | Symmetric Custom Slots |
| Offset Dual Groove Silicone | 2 Reinforced Barriers | 92% | Excellent | Offset Non-Standard EV Connectors |
Low-quality rubber ages and hardens quickly in extreme weather. Charging guns lose sealing elasticity during cold winter days. Water ingress creates severe electrical safety hazards. I had to find a stable material.
Choosing custom rubber parts materials requires checking compression set resistance and weather durability. High-elasticity silicone stays flexible from -40°C to 200°C, ensuring tight sealing even after repeated plugging cycles.
I conducted outdoor weather tests on various rubber materials for six months. Standard NBR rubber showed significant elasticity decay after thermal cycles. This reduced insertion force and caused loose seals.
I chose high-grade liquid silicone material. This material complies with the ASTM D395 compression set standard. It maintains a very low permanent deformation rate. Even after tens of thousands of plug cycles, it recovers its original shape quickly. I checked the Custom Silicone Sleeve design guide to set silicone hardness at Shore 55A. This hardness range guarantees smooth handling and provides sufficient compression force.
Here is my comparison table of common industrial seal materials:
| Material Name | Temperature Range | Compression Resistance | Electrical Insulation | Recommended Application |
|---|---|---|---|---|
| NBR Rubber | -20°C to 100°C | Medium | Fair | Industrial Oil Lines |
| EPDM Rubber | -30°C to 130°C | Good | Good | Automotive Door Weatherstrips |
| High-Elasticity Silicone | -40°C to 200°C | Excellent | Excellent | EV Charger Offset Seals |
Selecting proper structures and materials solves custom sealing challenges. Offset dual-groove silicone rings resolve water leaks in non-standard interfaces. Custom Silicone Parts provide reliable safety for charging equipment.
Industrial manufacturing data in 2026 shows that over 85% of EV charging gun makers use custom shaped silicone seals in offset interfaces. These components comply fully with the SAE J1772 charging standard. I follow 4 clear steps:

About Me:
My name is Kunfa Ye, but my friends call me Jeff. I was born in 1986 under the sign of the Tiger. I started working in the silicone rubber manufacturing industry in 2014, and I now have fifteen years of experience. Over these years, I started from scratch and experienced every rise and fall in manufacturing. I know the hardships and rewards of entrepreneurship deeply. I always focus on professionalism and integrity in every project.
The silicone manufacturing industry seems ordinary, but it affects every part of industrial production. I know that trust stands behind every product, and trade relies on mutual success. Over the years, my proudest achievement is not achieving personal financial independence, but helping my clients optimize their supply chains and improve production efficiency. Their success brings me far more joy than personal achievements.
Now, I hope to give back to the industry—sharing experience, answering questions, and connecting resources. Whether you are a startup or an experienced industry peer, if I can help, I will do my absolute best. Because I always believe: the essence of business is the transfer of value, and true fulfillment comes from how much help you can bring to others.
