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 seamlessy with existing equipment.

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

Tunable diaphragm technology, a 3M invention, lets clinicians hear different frequency sounds by simply adjusting the pressure on the chestpiece. Hold the chestpiece 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 eartips conform to individual ears for an excellant seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes, and for safety, require a significant effort to remove.
