Ehle Pre-Cooler sandblasted 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 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 pre-cooler.
Thus if you don't have connector/stem and bowl separate, you still need:

• 1 x 18.8 mm connector/stem for the bong - as replacement for the downpipe
• 1 x 18.8 mm connector/stem for the pre-cooler
• 1 x 18.8 mm bowl for the connector/stem in the pre-cooler
