Custom Silicone Gasket for SIM Card Tray | Waterproof Sealing for Mobile Devices






Detail Information
At SiliconePlus, we specialize in custom liquid silicone rubber (LSR) gaskets designed to protect delicate electronic components from dust, moisture, and contaminants. Our silicone gasket for SIM card trays is engineered to deliver precise, durable, and waterproof sealing performance for smartphones, tablets, and communication devices.
High-Precision Molding for Tight Fit
Each gasket is produced using advanced LSR injection molding technology to ensure tight dimensional tolerances and seamless compatibility with the SIM card tray structure. This results in a secure and reliable seal that prevents water and dust from entering the SIM card slot.
Premium Silicone Material
Manufactured from medical- and electronic-grade silicone, our gaskets are resistant to high and low temperatures, UV exposure, and aging. The material is BPA-free, non-toxic, and environmentally compliant (RoHS & REACH), ensuring safe use in consumer electronics.
Superior Waterproof & Dustproof Protection
The silicone gasket acts as a micro-barrier that blocks water, oil, and dust particles, effectively protecting sensitive circuits and SIM connectors. It provides IP67–IP68 waterproof rating compatibility, extending the lifespan and reliability of your device.
Customizable Design & Engineering Support
SiliconePlus offers full OEM/ODM customization — from color matching and durometer hardness to shape and thickness. Our engineering team collaborates closely with clients to develop gaskets that meet unique device specifications and assembly requirements.
