Replacement Tube by Reliance Medical fits Littmann® Cardiology IV® Stethoscope - Cardiology 4® (Blue)

This works like it should. Easy to exchange and makes your stethoscope as good as new. I’ve had difficulties with other tubing brands not being tight enough on the earpieces to keep a good seal, however, this one did not have that problem.

I wish this came with instructions for how to effectively remove the old tubing in order to complete the replacement. It's still sitting in the box until I can access better tools to get the job done.

Very nice. No regret. Sound is good, ear pieces are very comfortable.

Fit my Littmann Cardiology Bell.

You have to cut off the old tubing. Works great. Can't tell the difference w/ this and Littman

You get what you pay for. The metal tubes are wider than littmanns. The ear tips kept ripping and falling off. The sound quality was also inferior. I ended up paying the high price for genuine littmann tubing, but it was worth it.

Easy to replace.. good quality and love the color (blue)!
