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

These have saved me hundreds! Purchased my littman while in school and have just been replacing my tubing with these. Slides right onto my littman cardiology just pay attention to diameter when ordering. But yes buy this if youre needing a new tube. Its great quality and does not effect sounds.

Yep it's a great replacement. Wish there were more colors

This replacement tube exceeded my expectations. I was initially hesitant about buying it based on some of the reviews, but believe me, it is better than my original tubing. It's rubbery, and the sounds are clearer with this.

I bought this for my Cardiology iV stethoscope after my original Littmann tubing cracked, and it’s pretty comparable to the original. I use mine on the daily, and it’s held up for over 6 months so far. It’s actually a little more flexible than my original tubing, which I like - and the sound is pretty much the same. I’d order it again.

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

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.

I love my stethoscope and am so glad I could just replace the tube and not have to buy a new one! Big time save

Honestly this would make a great back up stethoscope. But to really use on a daily basis, it’s pretty damn mediocre. I didn’t want to give up the bell so this was a means to an end. But towards the end I did end up buying a 3M littmann replacement.
