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

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.

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

Was easy to install. Great buy.

I just wanted one. Didnt realize I was buying enough for my whole entire floor at the hospital. I usually dont complain about having too much...but at this rate I will still have loads left.

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.

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.

This fit my pediatric littman stethoscope perfectly. I've had my stethoscope for 14 years and these replacement parts worked perfectly! I'm so glad I found them bc I was dreading having to part with my tried and trusted stethoscope!
