A banger is a quartz bucket that drops into a dab rig and gets heated from the outside with a torch. The concentrate goes in it.
The floor decides everything, not the wall. A thin floor heats in seconds and dumps that heat just as fast. A thicker floor takes longer to bring up and then holds steady through the whole dab — which is why people running low temps like it. The wall is mostly about durability.
Check two things before you buy: joint diameter (14 mm and 18 mm are standard, 10 mm now and then) and gender — a male banger goes into a female joint and the other way round. Then the angle: 45° for rigs with a slanted neck, 90° for straight ones.
Maintenance is all about timing. Swab the banger with a cotton bud while it is still hot. Once residue cools it bakes on, and from there it is isopropyl and patience.
