This air tight glass collar adapter will allow you to use any 14mm male cone piece with any bong or joint that would typically require a 18mm male cone piece. Basically, this adapter will make the stem joint narrower. 14mm is the most common size cone piece sold globally so this adapter will come in useful more often than you may think. It will also allow you to use any 14mm ash catchers with your 18mm stems. Contact us if you require assistance with sizing.
