Learn About CPAP Hose Couplers & Connectors

Nearly every CPAP hose has a 22-millimeter connection cuff. This universal design ensures that most CPAP hoses are compatible with most CPAP masks and machines. There are, however, a few exceptions to this rule, such as ResMed’s AirMini AutoSet Travel CPAP machine, which was only compatible with a handful of masks before the Zephair AirMini Hose Adapter came along. Moreover, heated CPAP hoses usually have unique, proprietary connection shapes due to the power requirements of the heating coil, meaning that as long as the heated hose is designed for your specific machine, you won’t require an additional connector or coupler.

CPAP mask elbows, connectors, and adapters are typically mask-specific, and many of these components will already be attached to their respective mask at the time of purchase. You may need to replace these parts separately if they're worn or malfunctioning or if you need specific attributes to customize your sleep apnea therapy. For instance, if your tubing goes straight out the back of your machine, a Tubing Elbow Adapter can make more room on your nightstand and allow the hose to go exactly where you need it to.

There are a handful of universal hose couplers and connectors out there, but most will be proprietary for a particular mask, machine, or brand. 

Why Buy a CPAP Hose Coupler or Connector?

Here are a handful of reasons you might be interested in buying a hose coupler or connector for your CPAP machine:

  • You’re Looking to Replace an Existing Coupler or Connector
  • You Want to Reduce Tube Drag 
  • You Want to Add Oxygen to Your CPAP Therapy
  • You Want an Easier Magnetic Connection for Your Mask and Hose
  • You Want to Add a Swiveling Connection Point for More Freedom

Types of CPAP Hose Couplers and Connectors For Sale

You’ll find elbows, magnetic couplers, swiveling adapters, and oxygen enrichment adapters below for a wide range of uses, machines, masks, and hoses. Here are some of the most popular products we carry:

  • MedLock Magnetic Hose Connector: Add a magnetic coupler to your mask and hose connection if it isn’t able to quickly disconnect. Includes a magnetic dock to help keep your nightstand organized. 
  • Oxygen Enrichment Adapter: Easily add oxygen to your CPAP therapy. Simply insert between your machine and CPAP tubing or your tubing and mask if you’re using a heated hose and connect your continuous flow oxygen supply.
  • Pressure Valve: If you’re having issues with water from your humidifier flowing back into your machine, this product will prevent it from happening. 
  • Tubing Elbow Adapter: Allows you to route your hose directly to you from your machine, reducing nightstand clutter and drag. 
  • CPAP Hose Coupling Swivel Adapter: Adds a swivel between your mask and hose, hose and machine, or two short hoses for more flexibility and freedom of movement.

If You Need It, It's An Incredible Addition.

I don't need this at our home's elevation, but up at the cabin at 10,000 feet it really helps to add some O2 to help us old folks sleep.

Nice Adapter

This is a very handy product! The hose on my CPAP was always getting twisted and causing problems. Swivel adapter, problem solved at a very small price.

Great Product For The Price

I bought two ResMed CPAPs. An Air Sense 10 AutoSet and an Air Start 10. The hose connects to the back of the CPAP and then curls around a full 180 degrees. This reduces the curling by half. A vast improvement. Well worth it.

Great Improvement!

This Adapter is SO much better than the one I had which kept coming out of the machine in the middle of the night or at the slightest movement of the hose.
