Self Fusing Silicone Tape – Waterproof Pipe & Hose Repair

Multipurpose Waterproof Self Fusing Silicone Tape

Meet the go-to repair tape for homeowners, DIYers, auto enthusiasts, and marine hobbyists. This self fusing silicone tape bonds to itself without adhesive — simply stretch, wrap, and overlap to create an airtight, waterproof seal on pipes, hoses, roofing, automotive parts, and marine equipment. Made in Mainland China from high-grade silicone rubber, it delivers industrial-level performance at an everyday price.

Why You'll Love It

• True Waterproof Seal: Silicone rubber construction creates a watertight barrier that withstands moisture, humidity, and water pressure — ideal for quick pipe and hose fixes.
• Extreme Temperature Range: Performs reliably from -60°C to +260°C (-76°F to 500°F), making it suited for both frigid outdoor conditions and high-heat engine bays.
• High Dielectric Strength: Rated at ≥400V/mil, this tape provides dependable electrical insulation for wiring, connectors, and conduits in vehicles, watercraft, and home systems.
• No Adhesive, No Mess: Fuses only to itself — leaves zero residue on your pipes, hoses, or cables. Once bonded, it stays put and won't unravel.
• Impressive Stretch & Strength: With ≥300% elongation and ≥4.9 MPa tensile strength, this tape conforms easily to irregular shapes and tight curves without tearing.
• Versatile Applications: Use it on water pipes, garden hoses, automotive hoses, roof seams, marine fittings, electrical connections, and more — indoors or outdoors.
• DIY-Friendly: No special tools required. Stretch, wrap, and you're done — even for first-time users.

Frequently Asked Questions

Q: Does this self fusing silicone tape use adhesive to stick?

A: No — this silicone tape is completely adhesive-free. It fuses only to itself through a molecular bonding process when stretched and overlapped. This means it leaves no sticky residue on your pipes, hoses, or cables, and will not slip or peel once applied correctly.

Q: What surfaces can I use this waterproof silicone tape on?

A: This tape works on a wide range of surfaces including metal pipes, rubber hoses, PVC conduit, fiberglass, and most smooth surfaces. It is suitable for automotive, marine, plumbing, roofing, and electrical applications both indoors and outdoors.

Q: Is this tape safe for high-heat applications like engine hoses?

A: Yes. The tape is rated to withstand temperatures up to 260°C (500°F), making it suitable for engine bay hoses, exhaust-adjacent fittings, and other high-temperature environments. It also performs in extreme cold down to -60°C (-76°F).

Q: How long does one roll last on a typical repair?

A: Each roll provides approximately 1.5 meters (about 5 feet) of tape. For most small pipe or hose repairs, one roll is sufficient. For longer repairs or wrapping thicker sections, multiple rolls may be needed for full coverage and a proper seal.
