## Long description

WELDTITE DR SLUDGE inner tube 700 x 28c–35c with integrated puncture protection fluid and Schrader valve is designed for road and hybrid bicycles with tyre widths from 28 mm to 35 mm. The tube fits standard 700C wheels and combines the convenience of a conventional butyl inner tube with an internal sealant that helps block small punctures and slow leaks. Intended for daily commuting, training and touring, this inner tube aims to reduce stoppages from common road hazards without requiring specialist tools or installation techniques.
Advantages
The integrated puncture protection fluid provides continuous protection against small punctures and helps seal slow leaks, reducing the need for immediate roadside repairs. A Schrader valve allows easy inflation at most pumps and service stations. The tube’s dimensions cover a common range of tyre widths for road and hybrid bikes, offering compatibility and straightforward replacement. Made from butyl rubber, it balances airtightness and flexibility for reliable performance across varied road surfaces.
Suitable for
Commuting on paved and mixed urban roads
Road and hybrid bike training rides
Weekend touring with variable surfaces
Riders seeking reduced puncture interruptions without tubeless conversion
Key specifications
Inner tube size: fits tyres 700 x 28c–35c
Valve type: Schrader valve
Material: butyl rubber inner tube with internal puncture protection fluid
Compatibility: standard 700C wheels for road and hybrid bicycles
Protection: designed to seal small punctures and slow air loss
How to use
Inspect the tyre and rim for sharp objects before fitting. Slightly inflate the tube to give it shape, then insert it into the tyre mounted on a 700C rim. Ensure the valve passes straight through the rim hole and secure the tyre bead evenly around the rim. Inflate to the tyre manufacturer’s recommended pressure, checking for even seating and any signs of pinching. The internal sealant is active once the tube is installed and the wheel rotates; occasional riding and wheel rotation help distribute the fluid to potential puncture sites.
Usage recommendations
For best results, fit the tube with clean tyre interiors and remove embedded debris. Maintain recommended tyre pressures to reduce pinch flats and inspect the tyre regularly. If a large gash or repeated leakage occurs, replace the tube rather than relying solely on the sealant. Store spare tubes in a cool, dry place away from direct sunlight.
