Description
Product Overview
Custom LSR overmolded automotive single wire seals are designed to provide reliable waterproof and dustproof protection for automotive connector systems.
The single wire seal is manufactured by molding liquid silicone rubber around individual cable wires to create a controlled sealing structure inside connector cavities.
Compared with traditional loose rubber seals, LSR overmolding provides better dimensional stability, consistent sealing performance and improved assembly reliability.
SiliconePlus supports OEM/ODM single wire seal development based on customer drawings, samples and connector requirements.
Why Use an LSR Single Wire Seal
Automotive connectors often require individual wire sealing to prevent moisture, dust and environmental contamination from entering the electrical connection area.
A properly designed silicone single wire seal can provide:
• Waterproof protection
• Dust resistance
• Stable wire positioning
• Vibration resistance
• Long-term sealing reliability
• Improved connector assembly performance
