'Black Leaf' Recycle - Precooler

Description:

'Black Leaf' - Precooler - Prefilter

This precooler from 'Black Leaf' not only cools the smoke through the recycle function - the water is drawn into the small secondary chamber when inhaled and flows back through the upper pipe into the main chamber - but also through the adapter with NS 29 and drum percolator. This makes the inhaled smoke softer and is more gentle for the lungs.
Thanks to the supplied adapter, the precooler fits on bongs with 14er and 19er cut.
