GRAV® 14mm Adjustable Downstem

4 reviews
The 14mm GRAV® Adjustable Downstem can extend anywhere from 4" to 6" and is compatible with any 14mm beaker or straight-based water pipe with an angled joint. The two halves of the downstem are held together by a custom fitted segment of heat shrink tubing. Its tri-cut showerhead diffuses smoke through water, and its adjustable length is perfect for any amount of water.

Adjustable DownStem That Works

This thing works fine for 14/18mm sized pipes. Good solid glass that extends from 3" size to 6". The very end of the tube has a perc ball head. Cool GRAV logo on the side and the heatshrink that holds it all together also has the GRAV logo and some strange symbols. My only complaints are 1) I wish the half inch extension on the outside wasn't there and was flush instead. 2) 14mm female joint needs to have the glass frosted not crystal/smooth. So they frosted the 18mm male joint but left the 14mm female joint clear so now my ash catcher spins very easily instead of keeping tight. 3) the inside adjustable glass tube & perc head are almost too small and makes pulling drags off the bong harder.

Adjustable showerhead

I'm shocked this is an actual Grav product this downstem is a nightmare i had many problems with it.began with the "tubing"I believe it was called the bottom would fall out until it started corroded and cracked in several places i tried replace the tube put tubing over it untill it was so bad I had to tape it n its just bad I've hit Grav labs bongs enough times n had a downstem "a fixed one" always was impressed with the function and this guy just isn't the same quality in my opinion..

Love it but...

I’m having the same problem as the other review I was hoping to see if you sold the rubber pieces by themselves so I could replace you guys should totally start selling them anyways love the stem

Awesome concept.

Awesome concept. Neat novelty. Works right for about 2 weeks before the rubber expands and the pieces no longer fit snuggly enough to hold together. Now it's useless. Wax helped for a couple of minutes! :|
