Tubing Care

The majority of tubing used on Littmann stethoscopes is made of PVC (polyvinylchloride) which becomes hard when exposed for long periods of time to the lipids found in human skin. Wearing the stethoscope around the neck may cause stiffening of the tubing over time. If worn around the neck, we recommend wearing the stethoscope over a collar, away from contact with your skin.
