Review: Perfect replacement for cardiology iii - Had to replace the tubing on my cardiology III. Love the price and color of it. Had no problem replacing it. No complaints. And it comes with an extra pair of ear pieces for it. Hopefully I don't need to replace it any time soon (first time replacing the tubing), but if I do I will be purchasing this again. The light makes the blue brighter under the light, which I love! Review: Tricky process - I wish this came with instructions for how to effectively remove the old tubing in order to complete the replacement. It's still sitting in the box until I can access better tools to get the job done. ## Features - Please note: Your original tubing shape should resemble the item image. Otherwise, it will not fit your bell. - Eartips: Large and Soft-Sealing. They are Latex-free. - Eartips to diaphragm is approximately 27 inches and ear tubes are chrome. - This has a Double Y yoke position to the diaphragm. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07X9MTGLM | | Best Sellers Rank | #190,500 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #262 in Stethoscopes | | Date First Available | September 2, 2019 | | Is Discontinued By Manufacturer | No | | Item Weight | 5.9 ounces | | Manufacturer | Reliance Medical | ## Product Details - **Brand:** Reliance Medical - **Color:** Blue - **Exterior Finish:** Chrome - **Item Weight:** 5.92 ounces - **Material:** Metal ## Images ![Replacement Tube by Reliance Medical fits Littmann® Cardiology IV® Stethoscope - Cardiology 4® (Blue) - Image 1](https://m.media-amazon.com/images/I/61zZj8Y8HcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect replacement for cardiology iii *by J***E on October 30, 2025* Had to replace the tubing on my cardiology III.

Easy to exchange and makes your stethoscope as good as new. I’ve had difficulties with other tubing brands not being tight enough on the earpieces to keep a good seal, however, this one did not have that problem. ## Frequently Bought Together - Replacement Tube by Reliance Medical fits Littmann® Cardiology IV® Stethoscope - Cardiology 4® (Blue) - 3M Littmann Stethoscope Spare Parts Kit – Black, Compatible with Classic III, Cardiology IV, CORE Digital, Includes Eartips, Adult & Pediatric Diaphragms, Non-Chill Bell Sleeve, 40016 - Replacement Tube by Reliance Medical fits Littmann® Cardiology IV® Stethoscope - Cardiology 4® (All Black) --- ## 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.vu/products/242701820-replacement-tube-by-reliance-medical-fits-littmann-cardiology-iv-stethoscope](https://www.desertcart.vu/products/242701820-replacement-tube-by-reliance-medical-fits-littmann-cardiology-iv-stethoscope) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-17*
