How to Measure a Diffuser

Many, if not most people have trouble finding out what size of diffuser they need. Pizbi Smoke Shop sells every size of diffuser you need for your water pipe, this guide will help you order the one you need.Pizbi Smoke Shop measures our diffusers from the joint. The joint would be the part that is glass and glass onto your water pipe. Most of the time, the sizes are 14mm and 19mm. (The area that only touches the water pipe glass) Please measure the end of the joint, to the end of the diffuser and choose that option for when you buy a diffuser. The diffuser to the left is a 19 to 19 that is 4.25" inches, and the one on the right is a 19 to 14 lo-pro diffuser. Lo-Pro diffuser are very flush with the water pipe, so the bowl is very close to the base of your water pipe. Lo-Pro diffusers are ONLY 19mm to 14mm. If you have a large bowl, 19mm, you will not be able to use this diffuser. Please choose the one on the left of the picture. If your water pipe has a 14mm entrance for a diffuser, then please order the 14 to 14 diffuser and pick your size.
