General description

One roll for emergencies and everyday repairs.

MF50 Anti Leak is a self-fusing silicone tape for emergencies and all-purpose repairs.

MF50 can be applied on a wide range of surfaces and is versatile in use, including leaking pipes and hoses, electrical connections, cables, hand tool handles and much more.

Anti Leak Tape is resistant to UV, fuel, water, oils, acids and a wide range of solvents.

How it works

The tape creates a permanent air-tight and water-tight seal immediately after application. It ensures anti-corrosive and electrical protection, is very easy to remove and leaves no sticky residue.

Step by step

Application guidelines.

01 Clean the surface from dirt, oil etc. before the application
02 Attach the beginning of the tape close to the damaged area and start wrapping around, with tension
03 Keep stretching the tape until a 50 % overlap is achieved: once overlapped, the tape will fuse
04 Finish the wrapping around the problem area and press the tape firmly into place
05 For high pressure leaks, wrap more: most hose repairs need 3 to 5 layers, wrapped 3 to 5 inches in each direction away from the leak point; additional layers add strength
06 For electrical wiring, do not stretch tightly: the tape is more resilient to abrasion when not overstretched

Removing: cut the tape using scissors or a knife. MF50 leaves no sticky residue.
