## Description

"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. The 3M Littmann Stethoscope Spare Parts Kit – Black, Compatible with Master Cardiology™, Includes Snap Tight Soft-Sealing Small Eartips, Tunable Diaphragm & Rim, 40011 contains a black rim and tunable diaphragm for chestpiece, in addition to two small (1/2 inch), black 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."

Review: Necessary replacement and they don’t disappoint - I have had to order these parts every couple of years and I really think they do a great job! I wish they lasted longer but honestly they do get quite a workout. Fits my stethoscope like a dream and I can hear like it’s new again.

### ⭐⭐⭐⭐⭐ Necessary replacement and they don’t disappoint
*by M***N on April 2, 2026*

I have had to order these parts every couple of years and I really think they do a great job! I wish they lasted longer but honestly they do get quite a workout. Fits my stethoscope like a dream and I can hear like it’s new again.

### ⭐⭐⭐⭐⭐ It works!
*by S***G on September 5, 2026*

Snapped right in place and revived my old stethoscope. Can’t complain!

### ⭐⭐⭐⭐⭐ rejuvenated 20 year old stethoscope
*by J***R on August 31, 2018*

My daughter is doing an internship, through high school, with a local doctor, who is also a family friend. He asked her to bring a stethoscope, and knowing I'd previously been a paramedic, he knew I'd still have mine. The ring around the diaphragm had deteriorated over the past 20 years since I bought it though, so it needed to be repaired. Placed the order and in less than 48 hours, my Littmann Master Cardiology was back in business. Perfect fit and an easy install. Tip... insert the diaphragm into the ring and then slip onto the bell as one piece. Tried to put the diaphragm on first, then the ring, but upon seating the ring, it pulled on the edge of the diaphragm, causing it to not fit evenly. Plus, new ear pieces are a bonus.
