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." ## Features - This Parts Kit ONLY FITS THE MASTER CARDIOLOGY STETHOSCOPE. - Replacement of eartips, and the tunable diaphragms on Master Cardiology stethoscopes - Quality and reliability in one convienient package - Contains one tunable diaghragm and rim assembly for the stethoscope chestpiece, Black ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B014GVC33U | | Best Sellers Rank | #8,811 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #5 in Medical Stethoscope Parts | | Brand Name | Littmann | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (2,404) 4.6 out of 5 stars | | Global Trade Identification Number | 00707387772987, 00707387773069 | | Item Highlight | Includes Snap Tight Soft-Sealing Small Eartips, Tunable Diaphragm and Rim Assembly | | Manufacturer | 3M | | Model Name | Master Cardiology | | Model Number | 70200788332 | | Number Of Items | 1 | | Part Number | 40011 | | Recommended Uses For Product | listening to heart/lung sounds, detecting abnormal body noises | | Unit Count | 1 Count | | Upc | 707387772987 | ## Product Details - **Brand:** Littmann - **Color:** Black - **Model Name:** Master Cardiology - **Recommended Uses For Product:** listening to heart/lung sounds, detecting abnormal body noises - **Unit Count:** 1 Count ## Images ![Littmann Spare Parts Kit for Master Cardiology, 40011, Black - Image 1](https://m.media-amazon.com/images/I/61hc9ywdPBL.jpg) ![Littmann Spare Parts Kit for Master Cardiology, 40011, Black - Image 2](https://m.media-amazon.com/images/I/71g6xZ6Ee5L.jpg) ![Littmann Spare Parts Kit for Master Cardiology, 40011, Black - Image 3](https://m.media-amazon.com/images/I/71iXlBFemkL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Necessary replacement and they don’t disappoint *by on Reviewed in the United States 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 on Reviewed in the United States September 5, 2026* Snapped right in place and revived my old stethoscope. Can’t complain! ### ⭐⭐⭐⭐⭐ rejuvenated 20 year old stethoscope *by on Reviewed in the United States 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. ## Frequently Bought Together - 3M Littmann Stethoscope Spare Parts Kit – Black, Compatible with Master Cardiology, Includes Snap Tight Soft-Sealing Small Eartips, Tunable Diaphragm & Rim, 40011 - 3M Littmann Classic III Monitoring Stethoscope, 5803, More Than 2X as Loud, Weighs Less, Stainless Steel Black-Finish Chestpiece, 27' Black Tube, Stem and Headset - 3M Littmann Cardiology IV Diagnostic Stethoscope, 6201, More Than 2X as Loud, Weighs Less --- ## 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/17969014-littmann-spare-parts-kit-for-master-cardiology-40011-black](https://www.desertcart.jp/products/17969014-littmann-spare-parts-kit-for-master-cardiology-40011-black) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-12*
