Littmann Master Classic spare parts kit

Keep your 3M Littmann stethoscope performing with this Master Classic/Cardiology spare parts kit. It includes a black rim and tunable diaphragm for the chestpiece, plus two small (1/2 inch) black snap-tight, soft-sealing eartips. The soft-sealing eartips conform to individual ears to provide an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the eartubes and, for safety, require significant effort to remove.
