3M™ Littmann® Stethoscope Spare Parts Kit for the Master Classic II Stethoscope contains a black rim and tunable diaphragm/rim assembly in addition to two small (1/2 inch), 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.
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.

Exactly what I needed to fix the broken diaphragm on my litman. Will be using stehoscope.com in the future. Super fast delivery got me back in service in no time.
The shipping cost was exorbitant.
Instructions for installing the spare part were unclear.
The repair kit that I ordered came faster than expected and was exactly as described.
My order was processed and shipped quickly. I will recommend this site to my friends and co-workers.
Quick fix and good as new !
Just wish I could get only the diaphragm. My earpieces never wear out.
Easy to order, quick delivery of the correct parts
Excellent service but too many emails after the purchase.
Parts fit perfect. So glad to have my stethoscope back in working order
