The Aspire Nautilus practically defined mouth-to-lung vaping. When the original Nautilus launched, it set the benchmark for what a tight, flavourful draw should feel like, and the BVC (Bottom Vertical Coil) design was the reason why. These replacement coils keep that legacy running. Five coils per pack, Japanese organic cotton wicking, and a vertical coil orientation that promotes even heating and consistent flavour from first puff to last.
The lineup covers six resistance options across the Nautilus and Triton Mini platforms. The 1.8ohm Nautilus BVC is the classic MTL coil that started it all. The 0.7ohm Nautilus BVC opens up the draw for a warmer, looser pull. The Triton Mini variants add a 1.2ohm, a 1.8ohm Clapton, and a Ni200 0.15ohm for temperature control. The newer Nautilus 2S 0.7ohm mesh brings modern mesh performance to the platform. Compatible with the Aspire Nautilus, Nautilus 2, Nautilus 2S, and Triton Mini tanks.

Understanding the BVC Coil Design
BVC stands for Bottom Vertical Coil. Unlike traditional horizontal coils where the wire runs sideways across the wicking material, the BVC design orients the coil vertically. This matters because it allows e-liquid to saturate the cotton more evenly from all sides, which translates to better flavour consistency and fewer dry hits. It also improves airflow through the coil chamber, producing a cleaner draw with less turbulence.
The Japanese organic cotton wicking is another detail worth noting. It handles heat better than standard cotton, resists burning at the edges, and breaks in faster. Most users will notice the coil hits its stride within the first few puffs rather than needing a long break-in period.
Which Coil for Which Tank?
Compatibility across the Nautilus and Triton Mini family can be confusing, so here is the breakdown.
Nautilus 1.8ohm BVC
The original. A true MTL coil with a tight draw and cool vapour. Best for higher-strength nicotine and anyone who wants the closest thing to a cigarette draw. Works in the Nautilus, Nautilus 2, and Nautilus 2S.
Nautilus 0.7ohm BVC
A looser, warmer draw with more vapour production. Still MTL territory, but on the open end. Pairs well with 6mg freebase or 10-12mg salt nic. Compatible with the Nautilus, Nautilus 2, and Nautilus 2S.
Triton Mini 1.2ohm
Mid-range resistance for a balanced MTL draw. Good flavour, moderate vapour, and solid coil life. Designed for the Triton Mini tank.
Triton Mini 1.8ohm Clapton
A Clapton wire wrap adds surface area for richer, denser flavour at the same tight MTL draw as the standard 1.8ohm. Made for the Triton Mini.
Triton Mini Ni200 0.15ohm
Nickel 200 wire for temperature control mode only. Do not use in standard wattage mode. Requires a TC-capable mod. Designed for the Triton Mini.
Nautilus 2S Mesh 0.7ohm
Modern mesh heating element at 0.7ohm. Brings improved flavour clarity and faster ramp-up to the Nautilus platform. Compatible with the Nautilus 2S.
Frequently Asked Questions
What devices are compatible with Aspire Nautilus BVC Replacement Coils?
Aspire Nautilus BVC coils are compatible with the Aspire Nautilus, Nautilus 2, Nautilus 2S, and Triton Mini tanks. The standard Nautilus BVC coils (1.8ohm and 0.7ohm) fit the Nautilus, Nautilus 2, and Nautilus 2S. The Triton Mini variants (1.2ohm, 1.8ohm Clapton, Ni200 0.15ohm) are designed specifically for the Triton Mini. The Nautilus 2S Mesh 0.7ohm is compatible with the Nautilus 2S.
How do you install Aspire Nautilus BVC Replacement Coils?
Unscrew the base of the tank from the glass section. The old coil will be threaded into the base. Unscrew the old coil and thread the new one into place. Hand-tighten only. Do not overtighten, as this can damage the o-rings. After installing the new coil, reassemble the tank, fill with e-liquid, and let it sit for 5 to 10 minutes to allow the cotton to fully saturate before vaping.
Which Aspire Nautilus BVC coil is best for salt nicotine?
The 1.8ohm Nautilus BVC coil is the best match for salt nicotine at 20mg or higher. Its tight MTL draw and low wattage pair naturally with the smooth throat hit of salt nic. The 0.7ohm coil works with lower-strength salt nic (10-12mg) for users who prefer a slightly warmer and looser draw.
How long do Aspire Nautilus BVC Replacement Coils last?
Coil life varies by usage and e-liquid sweetener content, but most users can expect 1 to 3 weeks from a single coil with regular use. The BVC design and Japanese organic cotton tend to offer slightly better longevity than many competing coils. Heavily sweetened e-liquids will shorten coil life regardless of the coil type.
What is the difference between the Nautilus 1.8ohm and the Nautilus 0.7ohm BVC coils?
The 1.8ohm coil delivers a tight, cool MTL draw with minimal vapour production. It is ideal for higher-strength nicotine and anyone who wants a cigarette-like experience. The 0.7ohm coil runs at higher wattage and produces a warmer, slightly looser draw with more vapour. It suits users who want a bit more warmth and openness while still staying in MTL territory.
Can the Triton Mini Ni200 0.15ohm coil be used in wattage mode?
No. The Ni200 0.15ohm coil is made from pure nickel wire and must only be used in temperature control (TC) mode on a compatible mod. Using it in standard wattage mode can cause the nickel to overheat, producing an unpleasant taste and potentially releasing harmful compounds. If the mod does not have a TC mode, do not use this coil.
What is the BVC design in Aspire Nautilus coils?
BVC stands for Bottom Vertical Coil. The coil wire is oriented vertically inside the coil housing rather than horizontally. This allows e-liquid to wick more evenly from all sides, resulting in better flavour consistency and fewer dry hits compared to traditional horizontal coil designs. It also improves airflow through the coil chamber for a cleaner draw.
Are Aspire Nautilus BVC Replacement Coils compatible with the Nautilus X?
No. The Nautilus X uses a different coil system (Aspire U-Tech coils) and is not compatible with standard BVC coils. The BVC coils covered here are for the original Nautilus, Nautilus 2, Nautilus 2S, and Triton Mini only. Always verify the specific tank model before purchasing replacement coils.
