My Adsoft™ eartips occasionally come loose from the binaurals. Why does this happen, and what can I do to make them more secure?

Older style Adsoft™ PVC eartips (included on all Adscope® stethoscopes manufactured prior to 2014) are equipped with a threaded insert. If your stethoscope is equipped with threaded eartips, periodically tighten the eartips to ensure security. You may apply Teflon™ tape, or clear nail polish to the binaural thread to improve security without compromising scope performance or jeopardizing warranty coverage. Do not apply the adhesive to the eartips. Before using stethoscope, make sure glue has thoroughly dried.  Should you have further issues with your eartips, or if you would prefer to receive our new silicon Adsoft™ Plus eartips with an adapter for more security, contact ADC for a complimentary replacement pair at info@adctoday.com or call toll-free at 1-800-ADC-2670.
