Air Outlet Tube Coupler and Retainer Clip for S9™ Series H5i™ Heated Humidifier

There is a gasket at the back of the water chamber area that gets worn down by repeated removal and replacement of the water tank. At some point it gets leaky and you hear a whistling noise as you breathe. This fixes the problem so easily and instantly.

When my air outlet tube coupler cracked, this was a perfect drop-in replacement. What more can you ask for? (Other than a part that doesn't fail, of course.)

i am very pleased with product and delivery time which was a lot faster than expected. The parts fit perfectly and now my machine is quite again. Thank you, A.

I called CPAP.com and the representative was very helpful in helping me determine the piece that I needed for my ResMed S9 Auto CPAP machine. The component arrived in 3 days and it was easy to replace. CPAP.com was much more helpful than the mfr. ResMed receptionist as they did not even try to assist me as I called them first not knowing the CPAP.com would have this coupler. I have used CPAP.com for years and they have always been very knowledgeable and willing to help. Thank you.

Nice replacement part, easy to replace.

Great price
