GRAV has made scientific glass since 2004 — clean borosilicate builds with consistent wall thickness, properly annealed joints and function-first design. Below you'll find GRAV water pipes, pocket bubblers, spoon pipes and bowls at Smokerolla, from $17 hand pipes to $270 showerhead water pipes, shipping fast from the US.
What makes GRAV different
The brand is built on scientific glassware principles rather than decorative styling:
Borosilicate throughout
Type 1 borosilicate — the same glass class used in laboratory equipment. It handles thermal cycling far better than soft glass, which is why GRAV joints survive years of use.
Consistent wall thickness
Cheap glass varies in thickness along the same piece, creating stress points that crack. GRAV holds consistent walls, which is most of what you pay for.
Scientific design
Fixed downstems, precise joint angles and functional percolation rather than ornamental arms. Less visually dramatic, more reliable in daily use.
Made since 2004
One of the longest-running American glass brands, which means replacement parts and standard fittings are genuinely easy to source.

Frequently asked questions
Is GRAV glass worth the price?
GRAV pieces cost more than generic import glass because of consistent borosilicate wall thickness, properly annealed joints and scientific design rather than decorative shortcuts. If you have broken cheap glass at the joint before, that is precisely what the extra cost addresses.
What is GRAV known for?
Scientific glass — clean, functional design with precise joints and consistent thickness, made continuously since 2004. The Helix line with its signature venturi-chamber mouthpiece is the design most associated with the brand.
What size joint do GRAV bongs use?
Most GRAV water pipes use a standard 14mm joint, with larger pieces at 18mm. Check the individual product page — and see our bong bowls and downstems for matching replacements.
Are GRAV pocket bubblers practical for travel?
Yes — the Slush Cup, Coffee Mug and Spherical pocket bubblers are designed to hold a small amount of water without spilling when upright, so they travel far better than a full-size bong while still filtering.
How do I clean GRAV glass?
Isopropyl alcohol (91%) and coarse salt, agitated gently with the openings plugged. Borosilicate handles this well, but avoid sudden temperature shocks — never pour boiling water into a cold piece.
