Compatible Replacement Tube by CardioTubes fits Littmann(r) MasterCardiologyI(r) and Littmann(r) Cardiology III(r) Stethoscopes - 7mm Binaurals Blue TUBING

Looks good, perfect fit for the bell.

There was a reviewer who stated it was single lumen and the sound quality was poor...I was skeptical. I spent some time studying the new tubing and the removed littman tubing. I found that both are single lumen at the end (which allows the chestpiece to slide into place) but the new tubing was too long on the end. I trimmed it so that there was equal distance from the point of the double lumen to the point it slides onto the chestpiece. My main mistake with installation was that I slid the chestpiece onto the tubing slightly crooked. This caused unequal sound in the two ears and was distracting. Because the bell flips it was nearly impossible to get it turned. My husband found you could hold the base of the chestpiece with pliers and turn the tubing with the other hand. This did the trick and the sound quality is great. I am in primary care and I need to hear murmurs and lung sounds. Is this as sensitive as the littman originally? I can't say for sure but it seems to be sensitive enough for my needs. I was hoping to switch out the ear pieces for the original littman but that is not possible. The metal portion of the new tubing does not taper and instead there is a plastic cap onto which the rubber pieces slide. They are not interchangeable but personally I think they are comfortable enough. Overall very pleased and happy to have saved so much money.

The yolk part of my Littman stethoscope recently broke. I don’t want to pay the hefty price for a new Littman, so figured I would try this out. Popped in my old Littman bell/diaphragm, and it’s like having a brand new one! Perfect length, weight and quality, and auscultation is comparable to my original, maybe even better! Great purchase and price!

Buen material. Reemplazado elTubo original de Littman Cardiology II y nada que envidiarle al original

Worked well with my Litmann Cardiology III. My tubes were getting holes and changing the tubes and earpieces made it work like new. Even better, the new tube was lighter and less stiff than the original one. I’m glad I didn’t have to shell out another $300 for a new stethoscope.

Bought this to replace my official Littmann replacement tubing after I managed to crack that too. The Littmann tubing cracked after 3 years. This tubing the spring broke after less than 1 year - and notably I took better care of it after having to replace tubing two times so quickly - stopped leaving it in my car, I keep it in a case instead of thrown in a bag, etc. Not worth the price difference if I have to replace it three times as often!

I have a Littman Cardiology 3 stethoscope that the original tubing was wearing thin on that O have had for 12 yrs. I bought this and have been very happy with it. It fits my bell/diaphragm perfectly and the ear pieces are comfortable. It also came with extra replacement pieces for future needs. Would recommend.

I was a little leary about buying this for my Littmann stethoscope. My tubing had gotten stiff from wearing it around my neck. I took a chance because of the savings. Works great. I bought a clip to carry it at my waist now, instead of around my neck. Would highly recommend it!!
