This Littmann Stethoscope Spare Parts Kit By 3M 40011 is a must-have for anyone in the healthcare industry. Made in the United States, this kit is of exceptional quality and is perfect for those in the cardiology field.
Parts did not fit the cardiology stethoscope that I bought them for. Not sure how I could have avoided the disappointment. I ended up buying a brand new replacement stethoscope as well as these parts so spent more doing the thing I wanted to avoid. Choose the size/brand carefully.
