3M LittmannStethoscope Spare Parts Kit – Gray, Compatible with Classic III™, Cardiology IV™, CORE Digital, Includes Eartips, Adult & Pediatric Diaphragms, Non-Chill Bell Sleeve, 40017

Q: Does this work for the cardiology IV?

Yes. All current Littmann stethoscopes (with the exception of electronic models) have similar components. The Cardiology IV has a 1.3 inch (3.3 cm) bell and a 1.7 inch (4.3 cm) chestpiece. The Classic III, which I purchased, has identical dimensions. Both share the same double-sided turnable diaphragms, such as this replacement kit contains.

Q: Will this fit cardiology model 3 purchased around 2003?

Hello - thank you for your question. Unfortunately, this spare parts kit will not fit that model. Please connect with our team at 1-800-228-3957 (Monday – Friday 7:30 AM – 6 PM CST) and they will be able to assist with providing the correct model number. We look forward to speaking with you soon.

Q: What is the diameter of each of the diaphragms?

Hi Julia! The Classic III Stethoscope has a double-sided tunable chestpiece. The approximate chestpiece diameters are: Adult side 1.7"/4.3cm Pediatric side 1.4"/3.4cm Let us know if you have additional questions!
