3M Littmann Stethoscopes offers the high quality that 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 Lightweight II S.E. stethoscope contains a black rim and tuneable diaphragm and a non-chill sleeve 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. This time-saving feature allows the healthcare provider to focus on the patient, while the non-chill diaphragm provides patient comfort. 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.
