Aspire Nautilus BVC Replacement Coils

There is a reason the Nautilus BVC has been around for years, and people still buy it. Aspire got the basics right early on: a vertical coil that heats juice evenly, lasts longer than most, and gives a proper mouth-to-lung draw that ex-smokers actually stick with.

These days, the range has grown to eight resistances, covering Kanthal wire and mesh builds, and they screw into everything from the original Nautilus tank to the newer Zelos M80 Kit. Five in a pack. Pick your resistance, screw one in, fill your tank, and you are sorted. Pirate Vapes ships them tracked with age-verified checkout across the UK.

Why do vapers choose this

• Genuine Aspire coils. They fit properly, seal properly, and taste as they should.

• Eight resistances. Tight MTL on nic salts, or a looser restricted draw on 50/50. Your call.

• The vertical coil design heats juice more evenly, so flavour stays cleaner, and the coil lasts longer.

• Works across a big chunk of the Aspire range: Nautilus, Nautilus 2, Nautilus 3, K3, Zelos 3, Zelos M80, and more besides.

• Five per pack, which is usually enough for a month or more if you prime them properly.

Aspire Nautilus BVC Replacement Coils Features

Eight Resistances, Plenty of Range

Most coil platforms give you two or three options. The Nautilus BVC line has eight, and they genuinely feel different from each other. The low-resistance mesh ones pull more vapour and run warmer; the high-resistance Kanthal ones are cooler and tighter, much closer to a cigarette draw. You can try a few and settle on the one that clicks for you, all without changing your tank.

What BVC Actually Means (and Why It Matters)

BVC stands for Bottom Vertical Coil. Most older coils set the wire horizontally, which meant parts of the cotton got more heat than others. Aspire turned the wire upright. The more the cotton touches the juice, the heat spreads out, and you get fewer dry spots. In practice, that means two things you actually notice: the flavour stays cleaner for longer, and you do not have to bin the coil as quickly. It was a big deal when Aspire introduced it, and the design still holds up.

The Mesh Options

The Aspire Nautilus BVC Coil Range offers eight resistance options, covering everything from RDTL vaping to a tight cigarette-style MTL draw. Lower-resistance mesh coils provide warmer vapour and more airflow, while higher-resistance Kanthal coils deliver a cooler and tighter vape.

• 0.3Ω Mesh – 23–28W, RDTL, best with 50/50 or Higher-VG E-Liquids.
• 0.4Ω Kanthal – 23–28W, RDTL, suitable for 50/50 or higher-VG e-liquids.
• 0.7Ω Kanthal – 18–23W, MTL/RDTL, works well with 50/50 or higher-PG e-liquids.
• 0.7Ω Mesh (2S) – 20–25W, MTL/RDTL, ideal for 50/50 or higher-PG e-liquids.
• 1.0Ω Mesh – 13–15W, MTL, best with 50/50 blends or nic salts.
• 1.6Ω Kanthal – 7–11W, MTL, suited to higher-PG e-liquids or nic salts.
• 1.8Ω Kanthal – 10–14W, MTL, designed for higher-PG e-liquids or nic salts.
• 1.8Ω NS Kanthal – 10–12W, MTL, made specifically for nic salts.

For the MTL Crowd

The 1.6Ω and both 1.8Ω Coils are where most ex-smokers end up. Low wattage, sips on juice, and a tight, cool draw that feels close to a cigarette. Pair them with a nic salt at 10 or 20mg, and they deliver a smooth, satisfying hit without much fuss. The 1.8Ω NS variant is specifically tuned for salts, so if that is all you run, it is the one to go for.

Swapping a Coil

Not complicated. Unscrew the tank base, pull the old coil out, screw the new one in, drip some juice onto the cotton through the side ports, reassemble, fill, and wait five minutes. That five-minute wait is the bit people skip, and it is also the reason they get a horrible burnt taste on the first draw. Just let it soak. Save yourself the hassle.

One Coil, Loads of Devices

Aspire has kept BVC compatibility going across a lot of their tanks and kits over the years. So if you own a Nautilus 2 and then pick up a Zelos 3 down the line, you are still buying the same coils. Less to remember, and you can buy in bulk knowing they will work across your gear.

Aspire Nautilus BVC Replacement Coils Flavours List

No flavour in these. They are bare coils. The flavour is whatever juice you put in your tank, and you swap it whenever you like.

Quick rule of thumb for pairing: the higher-resistance MTL coils (1.0Ω and above) work best with nic salts and thinner, higher-PG liquids. Fruits, mints, tobacco blends: all good on a tight draw.

The 0.3Ω and 0.4Ω coils handle a 50/50 or slightly thicker juice without trouble, and that is where you get a bit more vapour and warmth. Have a look through our e-liquid range and match to whatever resistance you are running.

How to Fit the Aspire Nautilus BVC Replacement Coils

1. Turn the tank upside down and unscrew the base. The old coil comes out with it, or sits loose once the base is off. Pull it free.

2. Screw the new BVC coil into the base. Hand-tight is enough. Cranking it will strip the thread.

3. Drip a few drops of e-liquid through the cotton ports on the side of the coil. You want the cotton damp, not drenched.

4. Screw the base back onto the tank, fill the tank with juice, and stand it upright for a good five minutes. Then vape. If the first draw tastes off, leave it another couple of minutes. Patience pays off here.

What's in the Box

Five coils, all the same resistance. That is it. No tank, no juice, no device. If you need a new tank glass or fresh o-rings, throw those in your order too while you are at it.

Which Devices Do These Fit?

Aspire Nautilus BVC coils work across a wide range of Aspire tanks and kits, including older Nautilus models and newer Zelos devices. The same coil platform is used across the range, making it easy to switch between compatible setups.

• Aspire Nautilus – Original Nautilus tank that introduced the BVC coil platform.
• Aspire Nautilus Mini – Compact version with the same coil compatibility.
• Aspire Nautilus Nano – Small Nautilus tank using BVC coils.
• Aspire Nautilus 2 – Updated top-fill Nautilus design.
• Aspire Nautilus 2S – Compatible with standard BVC coils and 2S mesh options.
• Aspire Nautilus 3 – Current-generation Nautilus tank.

One thing to watch: the Nautilus X is a different tank entirely. It uses Aspire's U-Tech coils, not BVC. If you have a Nautilus X, these will not fit. Check your tank before ordering. The rest of the Aspire line, including pods and coils for other Aspire Kits, is in our Aspire range at Pirate Vapes.

About Aspire

Aspire has been making vape hardware since the early days of the industry. The Nautilus tank, specifically, is the product that put them on the map. When the BVC coil came out, it genuinely changed what people expected from a mouth-to-lung setup: better flavour, longer life, fewer burnt hits. The platform has grown since then.

Mesh options, nic salt variants, compatibility with newer kits like the Zelos 3 and M80. But the core idea has not changed. A vertical coil in a well-made housing that does its job without drama. Parts are widely stocked across the UK, pricing is fair, and the coils work. That is really the pitch, and it is enough.

Stock Up and Save

Conclusion

The Nautilus BVC has stuck around this long because it works. Eight resistances give you real choice over how you vape, from a cool, tight MTL on salts through to a warmer restricted draw on 50/50 juice.

Mesh and Kanthal builds cover both sides. And the same coils fit the original Nautilus, the Nautilus 2, the 3, the K3, Zelos kits, and a good few others on top. Just make sure your tank is BVC-compatible (not U-Tech) and pick your resistance. Grab a pack from Pirate Vapes with tracked, age-verified UK delivery.

FAQs

How many coils are in a pack?

Five. All the same resistance. You pick which one when you order.

Which devices do they fit?

A lot. The Nautilus (original, Mini, Nano, 2, 2S, 3, 3SR, GT, GT 2), the K3, Nautilus AIO, Nautilus Prime X, Zelos 2, Zelos 3, Zelos M80, and even the Dotmod DotAIO. Your tank needs to be BVC-threaded.

What does BVC stand for?

Bottom Vertical Coil. The wire sits upright inside the housing, which heats juice more evenly and makes the coil last longer. Aspire pioneered this design with the Nautilus.

What juice should I use?

Stick to 50/50 or higher-PG across the board. The MTL coils (1.0Ω and above) are best with nic salts or thinner freebase. The lower-resistance ones (0.3Ω, 0.4Ω) can take a slightly thicker 50/50 without issue.

How long does each coil last?

Depends on you. A week to a fortnight is typical. Sweet or dark-coloured juices gunk them up faster. Priming properly on the first fill makes a genuine difference to how long they go.

Do I really have to prime them?

Yes. A few drops on the cotton, fill the tank, and five minutes of patience. Skip it and you will taste burnt cotton on the first drag. It is the single most common mistake people make with new coils.

Will these fit my Nautilus X?

No. The Nautilus X takes U-Tech coils, which are a completely different shape. These BVC coils will not go in.
