## Description

"3M™ Littmann® Stethoscopes offers the high quality that medical professionals expect, and each replacement part and accessory meets the same demanding standards. Conveniently packaged in kits that correspond to our stethoscope models, Littmann stethoscope replacement parts and accessories make repairs simple. Each item is carefully manufactured to work seamlessly with existing equipment. The 3M Littmann Stethoscope Spare Parts Kit – Gray, Compatible with Classic III™, Cardiology IV™, CORE Digital, Includes Eartips, Adult & Pediatric Diaphragms, Non-Chill Bell Sleeve, 40017 contains a gray single piece tunable diaphragm for both the adult and pediatric sides of the chestpiece, a non-chill bell sleeve, and two small (1/2 inch), gray Snap Tight Soft-Sealing Eartips. 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. This time-saving feature allows the healthcare provider to focus on both adult and pediatric patients. 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: The only replacement parts I trust! - You can't go wrong with genuine Littmann replacement parts for your Littmann stethoscope! I still have the Cardiology III that I bought with my first paycheck when I became a nurse. I have replaced the diaphragms a few times over the last 20 years, and I always purchase Littmann replacements. They snap in place easily and look exactly like the original parts. They fit perfectly and offer the same excellent sound quality I expect from Littmann products.
Review: Perfect fit - Fit my Littmann cardiology IV perfectly. High quality and easy to to assemble just pop it on. Good price

## Questions & Answers

**Q: Does this work for the cardiology IV?**
A: 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?**
A: 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?**
A: 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!

**Q: buenas   tardes   sera    compatible  con  classic  ii    y  con  classic  ii  se**
