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 – Light Brown, Compatible with Ligthweight II S.E., Includes Snap Tight Soft-Sealing Small Eartips, Tunable Diaphragm & Rim, Non-Chill Bell Sleeve, 40021 contains a Light Brown rim and tunable diaphragm and a non-chill sleeve for the chestpiece, in addition to two small, Light Brown 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 the patient, while the non-chill diaphragm provides patient comfort. Snap-tight, soft-sealing eartips conform to individual ears for an excellent acoustic seal and comfortable fit. Eartips snap firmly onto the ends of the eartubes and, for safety, require a significant effort to remove." ## Features - This Parts Kit ONLY FITS THE LIGHTWEIGHT II S.E.
