3M Littmann Stethoscope Spare Parts Kit – Classic II Pediatric Diaphragm Assembly, Includes Black & Gray Rim, Floating Diaphragm, 40012

Perfect fit for Litman

As a pediatrician, my stethoscope gets chewed on a lot, and the ring that holds the diaphragm finally split. Glad to find these replacements. It's a little hard to get the ring onto the stethoscope. Definitely put the diaphragm into it first as the instructions suggest.

Was easy to install. Great buy.

I own four Littmann stethoscopes. They are great. They also cost a lot. This kit works. I just think that for the cost maybe they could have thrown in a couple extra retaining rings or another diaphragm -- something to make two elastic rings that look like split O rings and a diaphragm worth the twenty dollars.

Perfect for my Littmann stethoscope. Perfect fit and excellent quality as hoped.

I was so bummed when my 20 Year old stethoscope’s diaphragm disintegrated. Repair kit to the rescue! I was able to easily replace it and the stethascope works like new!

3M Littmann Stethoscope replacement parts are excellent! A great find! These parts extended the life of my stethoscope.

The replacement diaphragm and rim are exactly like the original and come with both a gray and a black set so that the original stethoscope can be matched. It is very simple to change out the diaphragm and rim. The price is excellent.
