After wearing my scope for awhile, the tubing became rigid. What caused this, and is there anything I can do to restore its original pliability?

Under certain conditions, the PVC tubing used in our ADSCOPES when exposed to atmospheric ozone, combined with skin oils can become rigid. If you wear your scope around the neck, try not to let it come in contact with the skin. In addition, periodic treatment with a vinyl protector (such as Armor All) once a month may delay the process. Should the tubing in your ADSCOPE become rigid, return to ADC for complimentary warranty service.
