VOLSUN IP68 Silicone Rubber Cold Shrink Tube (Model: VS-40×130mm) is a premium insulation and waterproof sealing solution engineered for industrial users, engineering contractors and system integrators. Fabricated from high-performance silicone rubber, this cold shrink tube for base stations delivers industry-leading IP68 waterproof sealing, anti-aging and electrical insulation properties, addressing core pain points of outdoor cable connection failures, moisture intrusion and insulation degradation in harsh environments. With no special heating tools or additional adhesives required for installation, it enables rapid on-site deployment, making it the preferred choice for large-scale infrastructure projects with strict reliability requirements.
This waterproof cold shrink tubing boasts IP68 waterproof sealing grade, and has passed 1000 hours of UV resistance testing. It maintains stable performance in continuous operating temperatures ranging from -60℃ to 200℃, with excellent resistance to ozone aging, salt spray corrosion and harsh weather. For industrial clients, this means minimal maintenance frequency and reduced total cost of ownership for outdoor projects, even in coastal, high-UV or extreme temperature regions.
With a ~4:1 shrink ratio (up to 5:1 for specific scenarios), this UV resistant cold shrinkable tube fits a wide range of cable outer diameters from 12.0mm to 33.0mm. It retains permanent elasticity and radial pressure even after years of aging and environmental exposure, forming a tight, gap-free seal against moisture and water intrusion. This feature reduces inventory SKUs for project contractors, lowers stocking costs, and extends the service life of cable connection systems.
The tool-free design eliminates the need for heat guns or open flame operations, greatly improving construction safety and on-site installation efficiency, especially for remote base stations and hard-to-reach construction sites. It also features excellent tear resistance, with stable insulation performance throughout its service life, effectively reducing construction labor costs and project delivery cycles for business partners.
