Replacement Tube by Reliance Medical fits Littmann® Cardiology IV® Stethoscope - Cardiology 4® (All Black)

Works perfectly and has good acoustics as replacement tubing for my Littmann Cardiology IV stethoscope. I was worried that the low price point would mean poorer performance, but that is not the case from my experience with this product.

Great quality, fits in the stethoscope head and is not loose. The earpieces are well-made and have held up well as this is the second tubing replacement I have purchased. Save yourself some money and replace the tubing instead of buying a whole new stethoscope.

Perfect for when my tubing on my littman cardiac IV tubing cracked and I didn’t want to buy an entire new stethoscope. FWIW I’m a veterinarian and my stethoscopes get a lot of wear and tear so I’ll update my review if it doesn’t hold up.

Good replacement - nice quality. Replaced my Cardiology IV with this baby and saved me a bunch of money in the process.

I have a cardiology 3 bell and this fit perfectly as a replacement tubing.

I am a physician and find the sound quality with this tubing and ear pieces to be equivalent to the original Littman tubing although it is somewhat less thick.

It is a suitable replacement for my Littmann Cardiologist but it is definitely not a Littmann. With that I mean that it becomes stiff very quickly and although it is a fraction of the cost of true Littmann replacement tubing, it also lasts merely a fraction of the time. My Littmenn tubing lasted almost ten years, but I have had to replace this tubing basically yearly as It becomes stiff very quickly.

Excellent replacement, great sound quality at low price
