3M 2228 Rubber Mastic Tape 1 Inch x 10 Feet Black

The 3M 2228 Rubber Mastic Tape is a premium electrical insulation and sealing tape designed for moisture sealing and mechanical protection of wire and cable splices. This conformable rubber mastic tape provides excellent electrical insulation and corrosion protection in demanding applications.

Key Features:

• Highly conformable rubber mastic backing forms a moisture-tight seal around irregular surfaces
• Excellent electrical insulation properties for low-voltage applications up to 600V
• Superior resistance to UV, moisture, chemicals, and extreme temperatures (-60°F to 176°F)
• Self-fusing construction creates a unified insulating layer without adhesive
• Ideal for splicing and terminating electrical cables, especially in automotive, marine, and industrial environments
• Black color for UV protection and professional appearance
• Dimensions: 1 inch wide x 10 feet long

This versatile tape is commonly used for moisture sealing electrical connections in automotive wiring harnesses, marine electronics, HVAC systems, and telecommunications applications. The rubber mastic compound fills voids and provides a permanent environmental seal that protects against corrosion and electrical failure.
