3M Scotch 9225 Self-Fusing Silicone Rubber Electrical Tape, Transparent, 33 m x 25 mm, 0.5 mm Thick, 1 Roll

Electrical technicians and maintenance crews rely on 3M Scotch 9225 self-fusing silicone rubber tape for insulating splices, repairing damaged cable jackets, and sealing connections in harsh environments. The tape bonds to itself without adhesive, forming a homogeneous, watertight layer that withstands temperatures from -50°C to 180°C.

Why choose it

Unlike conventional adhesive tapes, this tape fuses to itself, eliminating sticky residue and ensuring a permanent, void-free insulation. It remains flexible at extreme cold and resists UV, moisture, and chemicals, making it ideal for outdoor and industrial applications.

Ideal use cases

• Insulating and sealing electrical splices up to 8 kV/mm
• Repairing damaged cable jackets and harnesses
• Corrosion protection for pipes and fittings
• Emergency repairs in wet or oily environments

Good to know

The tape is RoHS compliant and leaves no residue upon removal. For best results, stretch the tape while wrapping to activate self-fusion.
