Downstems, precoolers are the lower spare parts for the water bongs. All spare downstems and precoolers for glass bongs are handblown in our craft shops. Skilful glassblowers use only hard borosillicate Pyrex glass. Our spare downstems and precoolers for glass bongs are ended with few tiny holes called a diffuser. Diffusers make many smaller bubbles and provide better smoothness of smoking.
What is a spare precooler for glass bong?
Spare precoolers for glass bongs are extra water chambers that consist of two pieces. One is a classic one piece stem with a bowl and a small handle for easier manipulation and the second piece is an extra chamber for the water, which works as an extra filtration. Spare precoolers for glass bongs are made especially for our precooler bongs but can be surely used with any other glass bong if the parameters match.
