Patch Kit WELDTITE RED DEVILS SELF SEAL 6-size self-adhesive inner tube patches, box of 20 (WLD-01021)

WELDTITE RED DEVILS SELF SEAL patch kit includes 20 self-adhesive inner tube patches in six sizes designed for repairing punctures on bicycle and light vehicle inner tubes. The patches are pre-glued and ready to apply to clean, dry rubber, enabling quick, glue-free repairs both on the roadside and in the workshop. The kit is compact and packaged for convenient storage, helping restore tube airtightness and extend the working life of inner tubes after puncture repairs.

Advantages

The self-adhesive patches eliminate the need for separate vulcanising cement, reducing preparation time and simplifying the repair process. Multiple patch sizes in one box provide options for a range of puncture diameters, while the pre-coated surface offers consistent adhesion and reliable sealing on most butyl and natural rubber inner tubes. The product is lightweight and easy to carry, suitable for emergency repairs and routine maintenance.

Suitable for

• Repairing punctures in bicycle inner tubes
• Fixing small leaks in inner tubes of light vehicles (e.g., scooters, wheelbarrows)
• On-road emergency tube repairs
• Workshop maintenance and quick service tasks

Key specifications

• Quantity: 20 self-adhesive patches
• Patch sizes: six different diameters included
• Application type: pressure-sensitive adhesive (pre-glued)
• Compatible materials: butyl and natural rubber inner tubes
• Packaging: compact box for storage and transport

How to use

Prepare the inner tube by removing it from the tyre and locating the puncture. Clean and dry the area around the hole; lightly roughen the rubber surface with sandpaper or an abrasive provided to improve adhesion. Select a patch size that fully covers the puncture with some overlap, remove the protective backing and press the patch firmly onto the tube. Apply steady pressure for several seconds to ensure contact and then allow the bond to set before reinstalling the tube.

Usage recommendations

For best results, use patches only on clean, dry surfaces and avoid stretching the patch during application. If multiple punctures are present or the rubber is brittle or heavily damaged, replace the inner tube instead of patching. Store the patch kit in a cool, dry place to maintain adhesive performance.
