Ehle Pre-Cooler orange, 2 x 14.5mm

This pre-cooler has twice a 14.5mm joint size, thus fits all 14.5mm pipes or with an adapter also 18.8mm 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.
The stem (without bowl) should have a length of maximum 12cm, better 11.5cm .
Thus if you don't have connector/stem and bowl separate, you still need:

• 1 14.5mm connector/stem for the bong - as replacement for the downpipe
• 1 14.5mm connector/stem for the pre-cooler - max. 12cm
• 1 14.5mm bowl for the connector/stem in the pre-cooler
