This 14-millimeter mouthpiece fits onto any 14mm male adapter and will convert it into a mini trumpet mouthpiece. There are not a lot of Grav pipes this piece will fit on, but it makes a nice addition to the modular systems they offer like the STAX or the Helix Multi. Replace the Helix chassis with this 14mm Trumpet Mouthpiece to get a straight shot of tasty smoke, or stick it on a 45° ash catcher for an awkward party.
