Need to change the size and gender of your joint? GRAV Labs presents a meticulously crafted glass adapter to do just that. This incredible piece can transform a female water pipe to a male water pipe with just one palm-sized accessory. A 10mm male tip slides right into the bong, and extends into a new 14mm male joint. This piece is commonly used to convert a dry herb bong into a dab rig. Interesting how such a compact item can double the value of your glass by upgrading to dual function. The frosted finish at each end secures the piece with a seamless glass-on-glass seal. Just a bit of friction anchors the device for an airtight flow with every inhale. DopeBoo offers a wide variety of low profile and dropdown adapters in all size and gender combinations. There’s no combo you can’t make happen. You might just find that opposites attract!
