3M Littmann Stethoscope Spare Parts Kit, Lightweight II S.E., Black, 40020

Fits right on my littmann. It was a little funky to put on but overall pretty easy. I have to say it doesn't feel like the fit it had when I first got the stethoscope but it's still a good fit. The sound to my ear is still just as good as when I first bought it. I couldnt detect any leaking air or looseness on the diaphragms but it does appear that there may be some moisture under the diaphragm. It wasn't there after I put it in and only appeared a couple days after. My point is...it's not good as new but it just as good and better than paying new price for it.

This fits the Littmann Cardiology Soft-Touch Chestpiece (STC). After years of use, I finally needed a new diaphragm. This was very easy to install and works perfectly. Wrap the larger ring around the diaphragm first, then “snap” it into place on the stethoscope using your thumbs to work your way down the edges. I was so relieved that I could just replace the diaphragm without having to buy a new expensive stethoscope.

I have been trying to find the STC rim for a while since the STC stethoscope is discontinued. I purchase the Lightweight II replacement parts for it, it fits perfectly. Therefore, I save and I have my stethoscope back.

I am so glad I got these! My stethoscope is brand new again! I really like the black more than the brown parts, that was a nice change.

100% original, I needed this since 1 or 2 years ago to fix the first stethoscope I had as medical student and here in México it is kind of difficult to find the replacements, so I'm very happy because I can use my very first stethoscope again!!

ordred this product but it did not fit my Littman stethoscope. It is the oblong shaped diaphragm, nothing wrong with it but just not what I need. also over priced found a lower price and matching color to my stethoscope. Had to send it back.

Fits my littman perfectly. It was just like new! Im so happy they sold parts instead of buying a whole new stethoscope. Ive had mine for 12 years

My littman stethoscope just cracked after 10 yrs of daily use. I trusted this product.
