How to use

Remove the visor from the helmet according to the manufacturer’s instructions, then detach the old face seal by gently pulling it from its retaining channel. Align the replacement seal with the visor edge and press it into the channel until it sits evenly around the perimeter. Reinstall the visor on the helmet and check the fit against the face, making any minor adjustments to ensure continuous contact along the seal. Regular inspection after installation helps confirm that the seal remains properly seated and intact.

Recommendations

Inspect the face seal periodically for tears, deformation or hardening and replace if any damage is found. Clean the seal with a mild soap solution and water; avoid solvents or abrasive cleaners that can degrade the material. Store spare seals in a cool, dry place away from direct sunlight to preserve flexibility and service life.
