14mm Female Ground Joint Connection.
Quality you can expect from an American Made glass product! Goo Roo Glass makes this daily drive oil rig with care and love.
Side car mouthpiece keeps the hot banger away from your face. This inline dab rig is made with quality and care. There are two reinforced welds that give it extra durability. The first connect the inline ground joint with the body of the water pipe. The second connects the inline mult-hole perc to the body of the water chamber.
Goo Roo uses holes instead of slits on their perc pieces. Many believe the hole design forces the smoke through the individual holes, and increases the diffusion. Smoke tends to escape through the first few slits on inline rigs with slit cut diffusion.
Take all of that and throw on a thick pedestal base, and this rig is built to be your daily driver.
