Grav 8″ Straight Base Bubbler with Orb Percolator


Out of stock

Grav, hands down are the masters of glass, scientific producers of glass if you will. A global reputation that is hard to surpass. Built to last, highly functional and as gorgeous as glass can get. Those in the know only and always use Grav glass. When Grav makes a water pipe/dab rig they know what they are doing. Built strong for a smooth and easy session. Oh, and so they don’t break easily either. Beautiful enough to display anywhere in your home, if that’s how you do things.


A fairly compact and minimal looking design. The base is thick and flat, helping to keep your piece upright and safe. As you move upwards this water pipe narrows incrementally (tiered) till you reach the extra thick reinforced mouthpiece, this design will help to keep water splashing up and out. 8” tall (20.5ish cms) and made on 32mm tubing makes this quite a durable glass piece.

The down stem is fixed and creates a 90° angle within the water chamber before culminating in the broad orb percolator. The included bowl is 14mm (removable male connection) in size with a frosted port for a nice airtight fit. This bowl is on the smaller side, perfect for those that like smaller rips.


Within the body of this water pipe is the fixed down stem. I find the design to be quite visually appealing as the down stem affixes to the exterior via 2 arms, one leading directly towards the orb percolator and the other simply affixing to the glass below. These 2 arms create a 90° angle mirroring the larger angle created within. Not sure if I described that well but it is pretty cool visually if design is your thing!

So, what is an orb percolator? Visually the orb reminds me of the New Years Eve Ball Drop that occurs in New York every year. 5 inlet holes at the base of the orb will diffuse your smoke, effectively filtering and smoothing out the smoke. Orb percs are considered to be a very effective way to diffuse your smoke. The better the diffusion process the more your large smoke bubble is broken up into smaller ones and the nicer/cooler the experience is.

TIP: To further ensure no splash back occurs Grav recommends filling with only 1.5” of water


Of course, Grav provides one of their high-quality flower bowls for you to use, a 14mm bowl (male) to be precise. This bowl sits to the side of the water pipe and attached to the down stem via a Dewar-seal joint that sits flush with the upper edge of the bubbler. There is a collar for easily handling. A smaller sized bowl for those that prefer their hits on the smaller side.


You have options when cleaning glassware, you can either use one of the myriad of prepackaged cleaning solutions (ensure you rinse thoroughly so no chemicals remain) or you can use my favourite method of Isopropyl Alcohol blended with Rock Salt (check out Higher Standards Salt Rox). The 2 work perfectly together to dissolve and abrade resins/gunk away. Rinse thoroughly and allow to dry.
