20mm Heat Coil Replacement (Axial Banger Style Coil)


20mm Heat Coil Replacement (Axial Banger Style Coil):

Your e-nail and/or coil may malfunction dangerously if the wiring order is not confirmed to match! Many e-nail controllers are wired differently (even though they look like they might match). If you are unsure, I can help you find out. Read this for more info.

  • 20mm axial barrel style banger heat coil with wraps on the bottom of the coil for direct lower surface heating
  • 100W/120V coil
  • XLR 5-pin connector
  • K-type TC’s
  • Kevlar cord sheath is rip and shear resistant
  • This is the wiring order of this coil: pin1=AC, pin2=AC, pin3=TC+, pin4=TC-, pin5=GND


If you don’t know for sure the wiring order on pins 1-5 of your gear please first ask your controller seller for the pin configuration to match to this coil before purchasing. If for some reason you cannot get a response, ask me and I will  see if we can figure it out together! Your e-nail will probably not work and likely even malfunction if the wiring order of the coil and controller do not match! It may look like the same size plug but some companies wire their e-nails differently to try to get proprietary exclusivity. If you do not know for sure how your e-nail or coil is wired, it is solely your responsibility to find out (how to here). Most e-nail sellers are responsive when you ask them. Just ask what the wiring configuration is on the 5-pin XLR plug. When you find it, please make sure it matches the listed configuration listed here.

Axial Coil Replacements

20mm heat coil replacements are here to: suit your upgrade needs from a barrel style to an axial style coil. An e-banger heat coil that has bottom-heating ability is a key piece of gear that gives you more temperature coverage across the vaping surface of your e-banger. If you own an e-banger or are thinking about switching from a torch to electric, the type of heat coil to use is worth considering. Typical barrel style coils leave the bottom surface cooler than the side walls. Flat coils leave the side walls un-heated. The axial coil swiftly combines to get two birds stoned at once (as Ricky says).

Best of Both Worlds

This can be compensated for by increasing the temperatures and avoiding the side walls with your tool; but often times this leads to an excess carbon buildup. On the side walls of your banger you may find black stains which seem to “soak into the pores” of the quartz and forever evade all cleaning efforts. This is mainly due to concentrate which does not get quite hot enough. If you do not remove this leftover residue, it will eventually dry and crust over– leading to “chazzing”. The bottom line is that it’s just plain easier and more efficient to heat the bottom more evenly to begin with.

Top reasons why an e-nail heat coil may fail to work correctly over time:

  • failed thermocouple (#1)
  • excessive/repeated bending/twisting of wires
  • broken solder connections
  • loose and bent XLR connection (plug)
  • excessive moisture contracting the coil
  • residue buildup near the seams– towards the fabric “sheath”
  • residue buildup at any other electrical connection (not as likely)
  • an exceptional amount of forceful plugging and plugging in of the cable — wearing down the terminals (not likely)
  • “thermal shock” (gradual wear)

Your 20mm heat coil replacement can stay working for years if care is taken to avoid sharp/stressful bending of the the cable, coil, or plug parts. They can be slightly bent and fitted with care not to break the thermocouple layer in the middle of the coil (like a twinky).
