Replacement Tube by CardioTubes fits Littmann MasterCardiologyI and Littmann Cardiology III Stethoscopes - 7mm Binaurals Green TUBING

Easy to install and works great-so much cheaper than the Littmann brand equivalent and worth every penny. The tubing is a lot more flexible and lighter weight than the Littmann cardiology tubing, but I actually prefer this as the Littmann gave me neck pain, and cracked within 4 years of use. Limited color options but I've actually had a number of coworkers ask me where I got this color tubing and have referred them to this! I have not noticed any loss in auscultation quality compared to the Littmann brand tubing! Great budget find

This was so much cheaper than a new scope and works just as well. There is a very strong plasticky odor that still hasn't dissipated despite more than a week out in the open. I'm hoping it eventually goes away because I'm not able to keep it around my neck like I usually do between patients. I have to carry it, which means I keep leaving it somewhere. If you're sensitive to odor you'll have a problem with this tubing.

I was looking for a replacement for my Littmann Cardiology 3 that I have had for several years (since 2008) that the tube had finally cracked on. I bought another cheap stethoscope that wasn't living up to my standards, and then also a Classic Littmann 3 that I was surprised didn't work as well as co-workers Classic 3's that I had tried (I think it was defective). Finally I thought I would try replacing the tube since I cannot find the Cardiology 3 for purchase anywhere under $200. This $25 tube works great with my Cardiology 3 bell and it is like having a brand new stethoscope that is just as good as my previous before the tube cracked. I wish it came in more colors, but really I'm overall pleased with price and quality.

The sound quality is really good, no complaints. Replacement was easy, just pull the diaphragm off the old tubing and attach to the new tubing.

For the price this is not a bad stethoscope. Not as sturdy as I would have liked. And sometimes you cannot hear breath sounds as clearly.

Very good quality for the price! Easy to assemble! Good sound!

Tubes are of good quality and work perfectly with my Cardiology 3 stethoscope. Problem is, they arrived with this bad kink in them. Emailed seller but no response. Did keep these out of necessity and will use them until I purchase a new set, but unhappy that I didn't get the courtesy of a return email. Buyer beware.

I’ve ordered these twice to replace my originals. I wear my scope around my neck most of the day, so oils eventually make the tubing crack. I love that I can replace just the tubing.My first replacement fit well and lasted about 2 years. My second set has a slight memory so it doesn’t lay as flat as my original and first replacement.Disappointed / bothersome enough I’ll look at other options before ordering a third time.
