3M PST Cold Shrink Connector Insulator 8428-12

The 3M™ Cold Shrink Connector Insulator 8428-12 is engineered to provide reliable primary insulation for solid dielectric insulated wires and cable splicing applications up to 1,000 volts. Utilizing 3M’s proprietary cold shrink technology, this insulator is pre-stretched on a removable core, allowing for quick and tool-free installation. Once positioned and the core is removed, the insulator contracts to form a moisture-tight seal, ensuring long-term durability and protection.

Key Features

• Easy Installation: No special tools or heat are required, simplifying the installation process.
• Secure Sealing: Maintains resiliency and pressure, even after prolonged exposure to environmental factors.
• Durable Material: Constructed from EPDM rubber, offering excellent resistance to acids, alkalis, ozone, and UV radiation.
• Versatile Application: Suitable for indoor and outdoor use, including direct burial and submersible applications.
• Temperature Resilience: Operates effectively within a temperature range of -40°F to 194°F (-40°C to 90°C).
