Replacement Tube by CardioTubes fits Littmann Master Cardiology and Cardiology IIIStethoscopes - 7mm Binaurals BLUE TUBING

Very Good and useful

Product quality, fit, finish, top notch.

I guess this the ultimate piece I was looking for replacement or DIY master cardiology stethoscope for enthusiast. Seems good, it's quite pricy as per Indian price. In this price we will get descent quality 2 to 3 stethescope in india. I wish littman precision master cardiology or IV cardiology stethescope bells are also available for order from same manufacturer. Plz keep the price bit reasonable and affordable. Littmans diaphragm and ear pieces are easily available but rest of the spares are not available for loose purchase. We are looking forward for replacement by other manufactures too.

Quality is low and manufacturing defect is that both yolk of set is not of equal length, not fit equaly on both ear and creat gap in ear.

​This is an excellent product that offers a perfect fit and performs superbly.

I got this tubing to replace the original of my Littmann Master Cardiology that got shredded a few years back under someone's snow blower while I was responding to a call as a Paramedic in Canada: it fits the head piece perfectly, and the auscultated sounds are very clear. It also came with replacement ear tips in different sizes, and also different diaphragms, they mostly fit the Cardiology III (which I have as well). Good bang for the buck.

Works very well to replace the tubing of my cardiology 3 littman stethoscope thats was all cracked! Unfortunately I lost the turquoise/ grey ear piece on one side in less then two weeks after receiving it. Is there any way to obtain another turquoise ear piece please (it comes with the grey pieces but not the turquoise)?
