Most CPAP hoses use a standard 22-millimeter connection cuff, ensuring compatibility with the majority of masks and machines. However, some devices, like the ResMed AirMini, have proprietary connections. Heated hoses also often have unique fittings to accommodate the heating coil.

Older masks that do not have swivel points built in where the hose connects to the mask may benefit from a coupler that adds a swivel point. This can provide greater flexibility and range of motion when changing sleeping positions. Modern masks typically do not require any kind of connector or coupler, though some people enjoy the added convenience of the optional MedLock Magnetic Hose Coupling Kit.

While there are some universal options available, many couplers and connectors are designed for specific masks, machines, or brands. To ensure proper fit and performance, it's essential to choose components compatible with your particular equipment.
