LOCTITE SI 5075 is a self-fusing silicone repair wrap for fast, temporary sealing and insulating jobs. The non-sticky tape bonds to itself rather than the substrate, forming a flexible, durable wrap around hoses, pipes, electrical connections, tool handles, and irregular shapes.
Key Features
- Self-fuses without adhesive, heat, or mixing
- Stretches up to 3× its original length for a tight conforming wrap
- Seals instantly when wrapped with the proper overlap
- Wide operating-temperature range: -65°F to 500°F (-54°C to 260°C)
- Electrical insulation with dielectric breakdown strength up to 15.7 kV/mm at 0.25–0.76 mm thickness
- Available in red and black 1 in × 10 ft rolls
Popular Uses
- Temporary flexible hose and pipe repairs
- Electrical insulation and connection protection
- Emergency automotive and industrial maintenance
- Wrapping tool handles and irregularly shaped components
- Sealing and bundling where conventional adhesive tape is unsuitable
How to Use
- Clean the area and remove loose contamination.
- Peel away the protective liner and press one end of the wrap in place.
- Stretch the tape tightly while wrapping around the repair area.
- Overlap each pass by approximately two-thirds of the tape width.
- Finish by overlapping the final pass onto the previous layer so the wrap can fuse to itself.

Important Limitations
This wrap does not bond to the underlying substrate; it must overlap onto itself to fuse. It is intended for temporary repairs, and the permanent component should be inspected or replaced as appropriate. Do not use in pure oxygen or oxygen-rich systems, or as a sealant for chlorine or other strong oxidizing materials. Always confirm compatibility and suitability for the specific operating conditions.
