Grace Glass Inline Diffuser Pre-Cooler
This beautiful glass precooler from Grace Glass is made from top quality, heat resistant borosilicate glass.
As smoke travels from the bowl through the network of chambers, it passes through the coloured glass diffuser where the smoke is broken up and cooled down before it reaches your bong's main chamber. This gives the user an incredibly smooth hit, free from the harshness one sometimes gets from using a waterpipe.
This precooler/diffuser has a standard 18.8mm male to female connection and 18.8mm bowl joint size.
The piece is finished with a coloured glass bowl and diffuser and the famous Grace Glass logo on the round chamber.
Quality bong accessory at a great value EDIT price, available in select colours. See drop down for colour option.
