Product Description
Enhance Valve Stability and Rim Protection
These Presta valve sealing gaskets are designed to address common issues like air leakage, rim hole corrosion, and debris accumulation. By adhering snugly around the valve stem, they form a barrier against dust, moisture, and vibrations, extending the lifespan of both your inner tubes and rims.

Technical Features

Material: Flexible silicone with strong adhesive backing ensures a permanent bond without residue.

Dimensions: 20mm (0.8in) outer diameter with a 6.5mm (0.26in) inner hole, suitable for rims up to 4mm (0.16in) thick.

Performance: Resists deformation under high tire pressure (up to 120 PSI) and remains effective in temperatures ranging from -40°F to 400°F (-40°C to 204°C).

Installation Guide

Clean the rim surface around the valve hole thoroughly.

Align the gasket's center hole with the valve stem.

Press firmly to ensure full adhesion, smoothing out any air bubbles.

Reapply if repositioning is needed—adhesive remains effective for multiple adjustments.

Ideal For

Cyclists seeking to reduce frequent tire pressure checks caused by slow leaks.

Riders tackling muddy trails or wet roads where debris clogs rim holes.

Maintaining aerodynamic efficiency by minimizing rim turbulence around valve stems.
