Ehle Pre-Cooler green, 2 x 18.8mm, Cylinder

This Ehle pre-cooler has twice a 18.8mm joint size, thus fits all 18.8mm pipes or with an adapter also 14.5mm pipes.
High quality processing. The glass is evenly thick, so it's less prone to break.
You put the Ehle pre-cooler into the connector (downpipe without bowl) of the bong.
You don't need an extra connector if you have stem and bowl separate.
Another downpipe or connector/stem with bowl is needed for the Ehle pre-cooler.
The stem (without bowl) should have a length of maximum 13cm .
Thus if you don't have connector/stem and bowl separate, you still need:

• 1 18.8mm connector/stem for the bong - as replacement for the downpipe
• 1 18.8mm connector/stem for the pre-cooler - max. 13cm
• 1 18.8mm bowl for the connector/stem in the pre-cooler
