Meaning that before it makes its way up to your mouthpiece, it has a chance to cool down a little! A lot of our pieces have multiple perc options as well as just the standard gridded, you're bound to find something that suits your needs! A gridded downstem is a type of percolator, it offers a way to filter your smoke through the small slits or grids on the base of the stem itself. You do not want any solution left on your downstem.Hey there! You have stumbled upon a fantastic section of our website, Gridded Downstems! Within these pages, you'll find stunning options for the classic filtration system commonly used on bongs.

A pipe cleaner, if available, will help scrub the insides better. Let the solution soak for two hours then shake. You will need to detach your downstem from the bong and soak it into a rubbing alcohol solution with salt for agitation. Make sure that the downstem is long enough to have the tip submerged in the water to produce bubbles, but not so long that the tip touches the glass. You can try using a straw to estimate the length a replacement will need to be if you do not have access to your bongs specification sheet. The downstem must be long enough to connect your bowl to the water in the main chamber of your bong - too short and it will not reach the water, too long and it simply won’t fit. The manufacturer will typically measure the downstem from the base of the joint to the tip. Downstem Lengthĭownstems come in many different lengths so it’s important to have one that fits properly.

You must insert a male bowl into the downstems female joint. The sizing won’t always be in this order so just remember that the “male” portion of the downstem is what goes into the bong, and the “female” portion will be the bowl size that you need for the downstem. For example a 14mm male to 18mm female downstem would work on any bong with a 14mm female joint and takes a 18mm bowl. The first number will be the bowl size and the second number the size of your bong joint. If the Downstem width is two small it will not form a proper seal, if the width is two large it simply won't fit! Your bowl will slide into your downstem and will normally take a slightly smaller bowl. The joint size is the measurement of the size of the hole the downstem rests on to form a seal, typically in the 10mm, 14mm, and 18mm range. Typically your bong specification sheet will contain all the details relevant to your downstem length and joint size. To get the correct downstem measurement you are going to need to know the joint size of your bong and the length of the downstem. These diffuser downstems can work in conjunction with your percolators to provide maximum filtration and more bubbles for smoother drags. Diffuser DownstemsĪ Diffuser Downstem uses a diffuser, an end with small slits, and functions much the same way as a percolator does to make your smoke smoother by forcing the smoke to make more contact with the water.


Fixed downstems can not be repaired when broken and will require the entire bong to be replaced (fixed downstems are also harder to clean.) Removable downstems, on the other hand, can be customized with different colors or diffusers and also be removed from the bong. The bong may have a fixed or a removable downstem. Your downstem may be fixed or removable and include a diffuser. Downstems are available in different lengths and sizes so it's important that you select a downstem compatible with your bong. You can read more about bowl sizing here. The downstem allows smoke to flow from the slide (bowl) into the main water chamber of the bong. Downstems may be found in many bong types to include beaker bongs and straight tube bongs.
