Replacement quartz bangers with thick walls and flat tops. Flat-top bangers have a level edge and work best when paired with bubble carb caps. Thick walls heat evenly and retain temperatures longer. These quartz-bangers all have polished joints that are easy to clean. Which leads to longer happier sessions.
