Conveniently packaged in kits that correspond to our stethoscope models, Littmann stethoscope replacement parts and accessories make repairs simple.

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: Worth the price. - This fits perfectly and is of the highest quality.

Just like new now! ### ⭐⭐⭐⭐⭐ Fit *by D***R on May 12, 2026* Worked much better than the last one. I can’t believe that I waited 7 years to replace it. Went on smoothly, perfect fit ### ⭐⭐⭐⭐⭐ Easy to put on and much more cost effective than buying a new stethoscope. *by Z***C on March 25, 2026* My first stethoscope was a gift from my sister when I was in nursing school. Unfortunately it had dried out after being cleaned so often during COVID and pieces started to get stiff and break. Since I could not afford to buy a whole new stethoscope I decided to try and just replace the pieces that broke. This replacement snapped on super easily and has not popped off since. It handled being used a cleaned frequently and outlasted my stethoscope that finally got too stiff to use comfortably. I’ll definitely buy this again if I need to replace more parts! ## Frequently Bought Together - 3M Littmann Stethoscope Spare Parts Kit – Gray, Compatible with Master Classic II, Includes Snap Tight Soft-Sealing Small Eartips, Tunable Diaphragm & Rim, 40023 - 3M Littmann Cardiology IV Diagnostic Stethoscope, 6165, More Than 2X as Loud, Weighs Less, Stainless Steel Rainbow-Finish Chestpiece, 27' Black Tube, Stem, and Headset - 3M™ Littmann® Stethoscope Identification Tag, Black, 40007 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/19681087-littmann-spare-parts-kit-for-master-classic-ii-40023-gray](https://www.desertcart.jp/products/19681087-littmann-spare-parts-kit-for-master-classic-ii-40023-gray) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-27*
