Bongs have a lot of different accessories and spare parts which we always have in stock just in case you would have an accident or if you simply want to increase your collection. The most common bongs are made of glass and usually consist of the bong itself, a pipe (called downstem, chillum or diffuser) and a bowl which you load with your herbs or tobacco. There are different models, sizes and lengths so that you can always find a spare part that fits your particular piece. A very important part that makes the smoking more comfortable are screens that are used in the bowl as a filter to prevent left-overs in the water. A bong can be upgraded with many accessories that make it extra pleasant to use, for instance with a precooler which filters and cools your smoke while preventing the waterpipe from getting dirty when using. If you're unsure about what you need you can always email our customer service and we'll help you finding the right parts!
