What Is a Cannabis Dab Rig? Parts, Heat, and Use Guide

A dab rig is a water pipe built to vaporize cannabis concentrate. You heat a quartz or titanium nail, touch a piece of concentrate to the hot surface, and inhale the vapor through water. No plant material burns. The concentrate turns to vapor at 315°F to 600°F.

Cannabis Dab Rig Reviews: Top Pick and Alternatives

Parts of a dab rig

• Nail or banger: the heated cup that holds the concentrate. Common materials are quartz, titanium, and ceramic. Joint sizes are 10mm, 14mm, and 18mm, male or female.
• Carb cap: a lid for the banger. It restricts airflow and drops pressure inside the cup, which lets the concentrate vaporize at a lower temperature.
• Water chamber: holds water for cooling. Most rigs hold 30ml to 100ml.
• Downstem: the tube that carries vapor from the banger into the chamber.
• Mouthpiece: the opening you draw from.

How a session works

1. Fill the chamber with water to a level above the percolator slots.
2. Heat the banger with a butane torch for 30 to 45 seconds.
3. Let the banger rest for 20 to 60 seconds. A banger that is too hot scorches terpenes and irritates the throat.
4. Pick up 20mg to 100mg of concentrate on a metal or glass tool.
5. Touch the concentrate to the banger floor, set the carb cap in place, and inhale.

Torch versus e-nail

A butane torch is the standard heat source. An e-nail replaces the torch with a heating coil and a controller. An e-nail holds a set temperature within about 10°F and removes the open flame from the table.

dab rig vs bong for cannabis

Dab rig temperature

Most users work between 450°F and 600°F. Below 400°F the vapor is thin and the puddle is large. Above 700°F the concentrate combusts and produces smoke instead of vapor. A dab thermometer or an infrared reader gives a real number. Torch time and cool-down time differ by banger thickness.

Cheap Cannabis Dab Rigs: What to Check Before You Pay

Size and shape

Most dab rigs stand 6 to 12 inches tall. A short vapor path keeps flavor. A large chamber holds more vapor and delivers a bigger hit per draw. Small rigs suit low-temperature dabs and single users.

Dab rig versus a bong

A bong is built for ground flower and uses a bowl. A dab rig is built for concentrate and uses a nail. Bong joints are often 14mm or 18mm and hold a bowl screen. Dab rig bangers sit in the same joint sizes, so some water pipes accept both with a swap of the accessory.

Cleaning

Pour out the water after each session. Soak a quartz banger in 91% isopropyl alcohol for 30 minutes, then rinse with water. Salt and alcohol remove residue from the glass chamber. A dirty banger tastes burnt and heats unevenly.

Law and safety

Cannabis concentrate rules differ by state and by county. Check the possession limit for concentrate in your state before you buy. Butane torches reach 2,500°F at the flame tip, so keep the flame away from clothing, hair, and curtains. Vent the room. Cannabis vapor is not smoke, but it still carries THC and affects driving and coordination.
