Great construction- wrong size

Order this for an old helix mini beaker. I guess the size i needed was a 10MM. This one was a 14MM. I ordered another Helix beaker in hopes this stem would would work in it. Diameter was fine, but the length was to long. If it fits your piece it is a really nice stem.

Good rip action - replacement for HELIX beaker downstem

GRAV Support recommended this size for replacement downstem that I needed for a HELIX beaker. This downstem goes ALL the way up to the wall of my beaker, touches it when putting it in. It works. Rips well, but a bit harder to draw from versus original downstem. Price was right too!

best downstem ever

great addition to a cheap piece in the meantime while you save up for a nice piece. hits ridiculously smooth. originally got the 4.5” thinking that was the entire length but was able to switch to the 3.3” over email before it shipped! great product, great service!
