The 12-pin Automotive Connector Gasket is a connector gasket manufactured by Guoming Rubber specifically for Deutsch DT 12-pin connectors. It has passed IP67 protection level testing and has already received sample orders from two domestic automakers and one Southeast Asian connector manufacturer.
I. Product Positioning: Targeting the "Precise Sealing" Needs of Multi-Pin Connectors "In the past six months, the demand for 12-pin connector seals from overseas inquiries we received has increased by 62%—customers reported that after enlarging the holes in traditional 8-pin seals, the gaps between the holes are prone to sealing failure, especially in the high-temperature environment of commercial vehicle engine compartments, where the failure rate is as high as 8%. This product uses red vapor-phase silicone material, with overall dimensions of 29mm × 15mm × 7mm. The diameter tolerance of the 12 pin holes is controlled within ±0.01mm, achieving a 'zero-gap fit' with the connector pins, structurally avoiding sealing leaks due to gaps between the holes."
II. Core Performance: Solving 3 Major Industry Pain Points in Multi-Pin Sealing Addressing the sealing challenges of multi-pin connectors, this 12-pin Automotive Connector Gasket achieves performance breakthroughs through three technological designs: 1. **IP67 Protection**: Passes IPX7 immersion test (30 minutes in 1 meter of water) and IP6X dustproof test, ensuring no dust or moisture intrusion in the port area, meeting the protection requirements of electronic components in the automotive cabin; 2. **Stable Operation in a Wide Temperature Range**: Withstands temperatures from -40℃ to 150℃, and can operate continuously for 3000 hours in a 120℃ engine compartment environment without hardening or cracking of the sealing lip; 3. **Low Compression Set**: After compression for 22 hours at 70℃, the deformation rate is ≤12% (industry average is 15%), ensuring long-term uniform sealing pressure across the 12 ports and preventing localized leaks. "A commercial vehicle connector customer tested three competing products. Two of them showed a deformation of 0.03mm in the hole gap after a high-temperature test at 150℃, while our product only deformed by 0.005mm, which fully met their standards."
III. Production Assurance: Automated Production Line Achieves "Stable Batch Production + Rapid Delivery" This 12-pin Automotive Connector Gasket is produced using Guoming Rubber's newly commissioned automated rubber mixing and injection molding production line. Key assurances include: - **Batch Stability**: CCD vision inspection instruments perform 100% inspection of the diameter and spacing of the 12 holes, resulting in a batch product PPM (defect rate per million units) of ≤25, far below the automotive industry's common standard of 50 PPM; - **Capacity Support**: Monthly production capacity reaches 300,000 sets, supporting flexible switching between "1,000 trial orders + 200,000 mass production sets"; - **Rapid Delivery**: Standard model sample delivery cycle is ≤7 days, and customized hole positions (such as 10-hole and 14-hole) can complete mold adjustment and sample production within 10 days.

Compliance and Service: To meet the procurement needs of overseas buyers, this 12-pin Automotive Connector Gasket has completed batch testing under the IATF 16949 system and is compatible with certification requirements in regions such as the Middle East (GCC) and Southeast Asia (SNI) (providing corresponding material testing reports). For overseas buyers, Guoming Rubber offers exclusive services: **Free Compatibility Testing**: Based on connector samples provided by customers, we can complete assembly and waterproof testing of the seals free of charge and issue test reports.
The widespread adoption of multi-pin connectors is forcing seals to shift from "general-purpose" to "precision-fitting." The mass production of 12-hole seals is Guoming Rubber's precise response to the trend of automotive electronics integration—Guoming Rubber can also customize Automotive Connector Gaskets to further cover the needs of the global automotive connector supply chain.
