The replacement headgear for the HC431 Full Face CPAP Mask is available in two different styles: headgear with two-point interlocking clips or headgear with one-point interlocking clips.
In both versions, the headgear is the same. The only difference is the number of interlocking clips. The two-point interlocking clips are the original style, while the one-point interlocking clips are the newer style.
With a criss-crossing pattern on the back of the headgear, you'll find this product provides extra support to keep your HC431 in place all night long.
Headgear Type Variations
The original HC431 headgear has a headgear clip with a 2 point interlocking system. The newer HC431 headgear has a headgear clip with a slim indention used to interlock the headgear to the mask.
Please Note: The 2 point interlocking system headgear is only compatible with the original style mask. The newer HC431 headgear is intended for the newer mask only. The mask and headgear cannot be interchanged.
