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.

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.

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!
