Silicone Rubber Customized Waterproof Cable Sealing Plug
High-performance rubber cable hole plug designed for superior sealing and protection in demanding industrial applications.
Superior Waterproof & Sealing Performance
Our cable sealing plug utilizes high-quality 94-V0 flame-retardant silicone rubber to achieve IP68 waterproof rating, effectively blocking moisture, dust, oil, and chemical contaminants. The material's excellent elasticity ensures tight compression fitting, maintaining stable sealing even in harsh environments including humidity, extreme temperatures, and outdoor exposure. Provides long-lasting protection for electrical components, preventing short circuits, corrosion, and performance degradation.
Excellent Material Properties
Silicone rubber material withstands continuous use from -60℃ to 240℃ with high tensile strength, tear resistance, and rebound resilience. Non-toxic, odorless, and compliant with international environmental standards, making it safe for food-grade equipment, medical devices, and household appliances. Excellent UV resistance, ozone resistance, and chemical stability adapt to complex working conditions in marine, industrial, and outdoor settings.
