Glass Reducer Stem Diffused


Product Description

Glass Reducer Stem Diffused 

The glass reducer downstem is made out of borosilicate glass, this is a six slit diffused downstem. This downstem converts an 18mm ground joint to a 14mm joint, it significantly shortens the glass sticking out from your bong producing a neater look. Slit diffusers are the most common form of diffused stems and provide a great smoking experience.

Product Details:

  • Joint Size: 18.8mm (SG18) – where stem fits in to water pipe
  • Bowl/Cone Size: 14.5mm (SG14) – where bowl/cone fits in to stem
  • Length: Choose from menu*
  • Material: Borosilicate Glass

*Lengths are approximate only and a few mm difference in either direction should be expected.
**Please be aware that the measured length is from the top of the ground joint to the bottom of the stem. (Please refer to image)
