(Use hot water or alcohol) Soften new tube with heat and mount over the metal neck How to Replace the diaphragm and rim Remove old rims and diaphragms with a long needle. Heat new rim with dryer until soft. (or very hot water) Fit new rim on head with the long needle. Reheat rim - center diaphragm over rim. ( Use needle to stretch rim over diaphragm. How to Adjusting the Binaural tension Hold each side of the metal ear tubes and gently and firmly pull them apart. Adjust until the ear tips are comfortable. If the ear piece feels too loose and the stethoscope keeps falling off you can make it tighter by squeezing the metal tubes together.

Review: Works for Littman Cardiology II - I needed to replace the tubing on my Littman Cardiology II that hasn’t been new since 1995. This is my second tubing replacement. The original was short and stiff so was prone to breakage. The second one was also a Littman but was way more soft and flexible and didn’t come with the metal ear piece replacement tubes. Anyway this one had the right price to allow me to keep my stethoscope which has sentimental value. The new ear tubes and pieces are great. The tubing was hard to get off the old stethoscope even with a hairdryer so I took a chance and cut it off. The new one went on easily thanks to a hairdryer dryer. The old one had the 2 holes on cross section and this had one but already I notice sound quality is the same. Listened to myself and detected a faint murmur. Not great but I heard it. This replacement tubing does the job.
Review: Excellent Quality Replacement! - I recently purchased the Compatible Replacement Tube by CardioTubes for my Littmann MasterCardiology stethoscope, and I am thoroughly impressed with its performance. Perfect Fit: This replacement tube fits perfectly with my Littmann stethoscope. The compatibility is spot on, making installation a breeze. I had no trouble swapping out the old tube for this one, and it feels just as secure and reliable as the original. High-Quality Materials: The quality of the tube is excellent. It feels durable and well-made, which gives me confidence that it will last. The material is flexible yet sturdy, allowing for comfortable use without compromising on performance. Improved Sound Quality: I noticed an improvement in sound transmission with this replacement tube. The acoustics are clear, making it easier to hear even the faintest sounds during exams. This is crucial for my work, and I appreciate how well it performs. Cost-Effective Solution: Replacing the tube instead of the entire stethoscope is a cost-effective solution. It allows me to keep my trusted Littmann stethoscope in service without breaking the bank. The price of this replacement tube is reasonable, especially considering its quality and performance. Overall Experience: Overall, I highly recommend the Compatible Replacement Tube by CardioTubes for anyone looking to replace their Littmann MasterCardiology tube. Its perfect fit, high-quality construction, and improved sound quality make it an excellent choice. I’m very satisfied with my purchase and will continue to use CardioTubes for my stethoscope needs!

### ⭐⭐⭐⭐⭐ Great replacement - sturdy, bright, and a little tricky to install
*by B***N on May 10, 2025*

This tubing works great as a replacement for my Littmann Classic II SE. The orange color stands out, which makes it way easier to keep up with. It’s flexible, sturdy, and sounds clear. I had to cut it down to size, but that was easy. The install was a little more difficult than I expected - I just peeled the old tubing off and forced the new one on bit by bit. I found out afterward that warming the tubing with a hair dryer can make the process a lot easier (wish I’d known that before). Still, even doing it the hard way, it fit securely and works really well.
