USB-C port waterproof gasket: help upgrade the protection of electronic devices
Product Overview
As the core component of waterproof and dustproof electronic devices, the USB-C port waterproof gasket is made of high-precision silicone/rubber material, and the annular sealing structure specially designed for the Type-C interface can effectively block liquid penetration, dust ingress, and oxidative corrosion. Our products have passed ISO certification, meet IP67/68 protection level standards, and are suitable for various charging equipment, smart wearables, automotive electronics, and other scenarios.
Core product advantages
Triple protection performance guarantee
Liquid protection: The density of food-grade silicone material is up to 1.2g/cm³, the wire diameter tolerance is controlled at ±0.05mm, and it can withstand continuous immersion in 1 meter of water for 1 hour
High temperature resistance: Operating temperature range from -50°C to 250°C, maintaining an elastic deformation rate of <5% in extreme environments7
Chemical resistance: 72-hour acid-base salt spray test (pH2-12), resistant to gasoline, alcohol, and other solvent erosion
Intelligent adaptation design
Precision structure: Provide 24P contact full coverage scheme, compatible with USB-C 3.1/3.2 interface protocol, to ensure the stability of 5A high current transmission
Size coverage: Supports ID 2.4mm to 12mm customization, suitable for mainstream brand mobile phones, tablets, and vehicle charging modules
Custom development services
We provide the whole process service from mold development to mass production:
Rapid proofing: 72 hours to deliver the first sample, support 3D drawings/physical reverse engineering
Material scheme: 8 kinds of materials can be selected, including NBR (oil resistant), FKM (chemical resistant), and LSR (medical grade).
Certification support: Assist in completing international certifications such as RoHS, REACH, UL, etc
