3M™ Littmann® Stethoscopes offers the high quality that medical professionals expect, and each replacement part and accessory meets the same demanding standards. Conveniently packaged in kits that correspond to our stethoscope models. Littmann stethoscope replacement parts and accessories make repairs simple. Each item is carefully manufactured to work seamlessly with existing equipment.

3M™ Littmann® Stethoscope Spare Parts Kit for the Classic III™, Cardiology III™, Cardiology IV™ & Core Digital Stethoscope contains a black single piece tunable diaphragm for both the adult and pediatric sides of the chest piece, in addition to two small (1/2 inch), black Snap Tight Soft-Sealing Ear tips.

Tunable diaphragm technology, a 3M invention, lets clinicians hear different frequency sounds by simply adjusting the pressure on the chest piece. Hold the chest piece with light pressure to hear low frequency sounds: press a little more to hear higher frequency sounds. This time-saving feature allows the healthcare provider to focus on both adult and pediatric patients.

Snap-tight, soft-sealing ear tips conform to individual ears for an excellent seal and comfortable fit. Ear tips snap firmly onto the ends of the ear tubes, and for safety, require a significant effort to remove.
