Weldtite Self Sealing Inner Tube Presta 700 x 18 - 25c

From Weldtite, the Self Sealing Inner Tube is designed for Presta-valve road bikes using 700 x 18–25c tyres, with anti-puncture sealant pre-filled into the tube at the correct dosage. It’s a practical choice for riders who want added reassurance on everyday commutes, training rides and longer days in the saddle, helping to reduce the disruption of unexpected punctures.

The water-based sealant is formulated with anti-corrosion properties and is described as completely harmless. When a puncture occurs, it seals instantly for holes up to 3mm in diameter, and is designed to work time after time, supporting more consistent riding between maintenance checks.
