Key benefits Reliable protection against water, dust and dirt to extend the service life of your equipment in harsh environments. Strong electrical insulation to reduce risk of short circuits and component degradation. Ready-to-use sizes and pre-cut lengths speed installation and reduce trimming errors. What makes it stand out Combination of a waterproof, dustproof and dirt-repellent design with high-performance silicone resin for long-term durability. Complete set of eight common sizes (1 mm to 10 mm) covering a wide range of small components and cable diameters. Pre-cut 40 mm lengths for consistent, repeatable coverage without measuring or cutting on site. Key features Material: Silicone resin—corrosion-resistant, heat-resistant and electrically insulating. Sizes: 8 specifications spanning 1 mm to 10 mm to accommodate different component diameters. Length: Each piece is pre-cut to 40 mm for fast, uniform installation. Function: Provides a protective, insulating barrier against moisture, dust and contaminants. Compatibility and performance Designed for use wherever compact, reliable sealing and insulation are required. The 1–10 mm size range makes the product compatible with many small wires, terminals, connectors and component leads. Silicone resin maintains insulation and resists degradation under heat and corrosive conditions, ensuring stable performance over time. Practical use scenarios Outdoor electrical junctions and sensor connections: protect splices and terminal points from rain, dust and airborne debris. Automotive wiring repairs and harness protection: insulate and shield small wires and connector ends from oil, grime and engine heat. Industrial control panels and field equipment: prevent moisture ingress and corrosion on small terminals and component leads in factories and plants. Quick installation tips Choose the size that most closely matches the component diameter (1 mm to 10 mm). Use the pre-cut 40 mm length for consistent coverage; trim only if a shorter length is required. Ensure surfaces are clean and dry before application for best sealing and insulation performance.
