replacement diaphragm and rim

Item was as described, arrived quickly, at low cost, fairly easy to install, and allowed me to r and r a used excellent condition stethescope at very low cost. Installation instructions did suggest talcum powder which I didn't have but did without. Might be nice to include a tiny pacet of the stuff with shipment.

Fast, easy search; Right product, right price

I came to Allheart's site via a Google search. I didn't have much to go on - the model number of my Littmann steth wasn't on the instrument - but with about five minutes of easy looking I found the right part I needed. Ordering was easy, shipping fast. Seven bucks seems a little steep for a shipping/handling charge - but I didn't have to drive anywhere or search for a parking space. All in all, satisfactory and satisfying.

I purchased a Littmann diaphragm and rim for 10.00 . It was easy to place on and my stethoscope,and works as good as it always did. Sure beats replacing parts than replacing the whole thing.

Thanks to Allheart, it came very quickly in the mail and was easy to assemble onto my back-up stethoscope. Tip: place the diaphragm into the outer rim first and then fit that unit onto your larger bell. Otherwise you will be working at it forever!!

I love the fact that I have owned and used the Cardiology III for over 10 years and all I needed to keep it going was a new diaphragm. This is an easy fix for a stethoscope that has been well loved and well used. A much better deal than purchasing an entirely new stethoscope!

I got just what I needed...... detail..... any company can have the big products but only the good companies have the detailed equipment! My Littmann would be useless without the diaphragm!

Littman tunable diaphragm

Excellent quality from Littman as usual. A little struggle to get rim on but fit perfectly once was able to adjust it on.
