3M Littman Tunable Diaphragm

Replaced my stethescope that was no longer under warantee. This is absolutely the way to go to not have to replace the entire set. I was able to replace the tubing and diaphragm, and keep the head which was most important to me. Absolutely great quality and I LOVE it!

Littmann Tunable Diaphragm

I've had my Littmann for 14 years. It's very durable and I can't imagine doing my job without it. So when the tube cracked three years ago I purchased that assembly through Allheart and was very pleased at the price and speed of delivery. Well the diaphragm cracked on the side about a month ago. I taped it together, but last week it just fell apart. While at work I ordered the replacement diaphragm and it came right away, on my day off, so I didn't have to work without my prized Littmann Master Cardiology! The diaphragm was on sale, arrived at my home in time, and works like a charm. I'm am very pleased! Thank you Allheart!

As with all the Littman products I have purchased over the years, this diaphragm worked like a charm! My old one was mysteriously broken while I was on Vacation! The new one was an exact fit to my treasured 20+ yr old graduation gift!

Great Value

My Master Cardiology stethoscope is quite old and the original rim was disintegrating. I was so happy that I could just buy a replacement diaphragm and rim and not have to shell out for a whole new stethoscope. It was very easy to assemble and now my stethoscope looks so new! AllHeart delivered my order very promptly and in perfect condition. I was very pleased.

Great replacement

Having spent a good amount of money for my stethescope several years ago it was nice to find someone who sold just the part I needed to make it brand new again at a reasonable price. I received excellent customer service over the phone when I needed it and I received the correct product in little to no time. Highly recommend ALL Heart for all of your healthcare/medical supply needs. If needed, I will use them again without hesitancy.
