Staple Coil – What is it in Vaping & How Does it Work?

Definition

A Staple Coil is a high-performance Sub-Ohm coil build made by stacking several flat ribbon wires (the “staples”) and wrapping them with a thinner round wire. Designed for rebuildable atomisers (RDAs, RTAs), its flat core maximises surface area, delivering intense flavour and dense vapour. Staple coils sit below 1 ohm, making them ideal for direct-to-lung vaping, but they are not recommended for a Kit“>Starter Kit because they demand high power and battery knowledge.

Technical Details

Construction starts with 8–12 lengths of flat Kanthal or Nichrome ribbon (typically 0.3–0.5 mm thick) clamped together like staples, then tightly wrapped with 32–38 gauge round wire. The flat core acts as a heat reservoir, while the outer wrap controls ramp-up time and creates tiny grooves that wicke-liquid efficiently. Final resistances usually land between 0.08–0.3 Ω, perfect for 60–120 W regulated Mod“>Squonk Mod devices with Short Circuit Protection. Variations include framed staples, staggered staples, and alien staples, each altering flavour and vapour production.

Usage & Tips

• Mount the coil with screws tight and centred; hotspots will mute flavour and shorten lifespan.
• Burn at 15–20 W to check for even glow, then Steepcotton in e-liquid before vaping.
• Use 3 mm Diameter“>inner diameter to balance wicking and airflow in most decks.
• Watch battery drain—high mass coils draw more current; never exceed CDR limits.
• If flavour drops, dry-burn gently and rinse; avoid metallic taste by replacing after 3–4 re-wicks.

History & Context

Originating on vaping forums around 2015, staple coils evolved from simpler Claptons as hobbyists chased denser clouds. Australian coil artists popularised the build in local comp scenes, driving demand for high-wattage Squonk Mod devices and premium, low-nicotine juices suited to these advanced coils.
