The Glass Bong Downstem 18.8mm 17cm is the tube that carries smoke from the bowl down into the water chamber of your bong. It is one of the higher-wear parts of any bong — glass-on-glass contact, regular in-and-out movement, and it lives submerged in water — so replacements are a practical purchase rather than an upgrade.

- Length: 17cm

The 17cm length suits taller bong bodies where a shorter stem would not reach the water properly. Correct stem length matters for filtration — too short and the smoke bypasses the water entirely. If you are unsure, measure the distance from the joint opening down to the base of your bong's water chamber before ordering.
