XMax V3 Pro & V4 Pro 2-in-1 Glass Mouthpiece & 14 mm Adapter

The XMAX V3 Pro & V4 Pro 2-in-1 glass mouthpiece lets you use the same top in two ways: draw directly through the glass, or fit its tapered end into a water pipe with a 14 mm female joint. The mouthpiece and adapter are one assembly, so there is no separate adapter to fit or carry.

Which XMAX model do you have?

• XMAX V3 Pro: choose this top if you want a glass mouthpiece for direct use and a 14 mm water-pipe connection in the same part.
• XMAX V4 Pro: the standard device already has a glass mouthpiece with a 14 mm connection. Choose this assembly to replace a damaged or missing top, or to keep a spare.

The box specifies V3 Pro and V4 Pro. The V3 Nano and Starry V4 are different models. For use with a water pipe, check the joint as well as the vaporizer: the 14 mm size refers to the glass connection.

What comes in the box?

One glass mouthpiece and 14 mm adapter assembly, including the base shown in the product photo. The vaporizer and water pipe are sold separately. If you are matching an older V3 Pro part, compare the photos with our V3 Pro glass mouthpiece and dedicated V3 Pro water-pipe adapter.

Fitting and care

Switch off the vaporizer and let it cool before changing the top. Hold the mouthpiece by its base when fitting or removing it. When connecting to glass, support both pieces and seat the taper gently; if it does not fit, check the joint size rather than forcing it.

Remove the mouthpiece from the device for cleaning and follow your model’s care instructions. Keep liquid out of the vaporizer, let the parts dry fully before refitting, and replace chipped or cracked glass. For other spares, browse our vaporizer parts and accessories.
