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 Master Cardiology Stethoscope contains a black rim and tuneable diaphragm for chest piece, in addition to two small (1/2 inch), black Snap Tight Soft-Sealing Ear tips. Tuneable 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. Snap-tight, soft-sealing ear tips conform to individual ears for an excellent acoustic seal and comfortable fit. Ear tips snap firmly onto the ends of the ear tubes and, for safety, require a significant effort to remove.
