The LG3HT is the integrated heated breathing tube for the React Health Luna G3 series, 1.8 m long with a 19 mm bore and standard 22 mm cuffs. It plugs into the device on a proprietary connection, and once fitted a Heated Tubing option appears in the machine menu, so the tube is powered and controlled by the Luna itself rather than by anything plugged into the wall.
What a heated tube does is hold the air above its dew point along the whole run from machine to mask. An unheated hose loses heat to the bedroom, the moisture the humidifier put into the air condenses on the inside of the tube, and it arrives at the mask as water. That is rainout, and it is the single commonest reason people turn the humidifier down or off and then give up on therapy because of a dry nose and mouth. With the tube heated, humidity can be run at the level the airway actually needs instead of the level the hose will tolerate.
The 22 mm cuffs are worth noting because they are the standard CPAP mask fitting. Any 22 mm mask connects straight onto this tube without an adapter, so changing mask brand does not mean changing tube. The 19 mm bore is the slim size rather than the older 22 mm bore, which makes the hose lighter on the mask and less inclined to pull the seal off during the night.
It is supplied new. The connection is specific to the Luna G3 series, covering the CPAP, APAP and BiPAP devices in that range, and it does not fit the earlier Luna G2.
