When a quick fix just won’t cut it, the Ultratape Extreme Silicone Tape steps up to the job. This heavy-duty silicone tape is your go-to for everything from emergency plumbing repairs to sealing electrical connections – all without a drop of adhesive.
Tough, flexible, and built to last, this black 25mm x 3m roll forms a permanent, moisture-proof seal by fusing to itself – no sticky residue, no mess. Whether you’re patching a leaky pipe, insulating wires, or improving tool grips, it sticks only to itself, creating a neat, airtight bond that’s fuel and oil resistant.
Designed for serious performance, it handles extreme temperatures from -50°C to +260°C, making it ideal for both indoor jobs and outdoor fixes. It’s UV resistant, flame retardant, and insulates up to 8,000 volts, offering peace of mind where safety counts. Better still, it’s WRAS approved and safe for use with potable water, so it’s perfect around the home or in the van.
With no adhesive to degrade or wear out, and self-fusing technology that outperforms heat shrink tubing, it’s a smart, reliable addition to any DIY kit.
Whether it’s a leaky radiator hose or a loose wire, this tape’s got you covered. Add it to your toolkit and be ready for life’s unexpected fixes.
