Aspire Replacement Tanks — MTL & Sub-Ohm Vape tanks

If your tank has started leaking, tasting burnt, or just does not hit like it used to, you do not always need to buy a whole new kit. Most of the time a fresh Aspire tank is all it takes to get things running like new again.

Here at Vape Online Store, we stock a proper range of Aspire tanks, and this guide is here to help you pick the right replacement without any of the confusing jargon.

 

Why Aspire Tanks Have Stuck Around So Long

Aspire is one of the oldest names in vaping, and the original Nautilus tank, launched back in 2014, is still talked about as one of the most influential MTL tanks ever made. Here's a fun fact — the Nautilus name has stuck around for over a decade now, with newer versions like the Nautilus X and Nautilus 3SR carrying the same core idea forward — simple, reliable flavour without leaks or fuss.

Aspire's tank range stretches well beyond just the Nautilus family too. Cloud chasers often look at the Aspire Odan tank for bigger direct lung hits, while the Aspire Onixx tank and Aspire K1 Plus cover the middle ground between flavour and vapour. For anyone after something even smaller, the Aspire Nautilus Nano tank is another popular choice worth knowing about. Whatever style you vape, Aspire has spent years building a tank to match it, which is exactly why so many people keep coming back to the brand for replacements.

 

How to Pick the Right Replacement Tank

Before buying a replacement, check what tank your current device actually uses, since Aspire coils are not always interchangeable between tank families. Think about how much e-liquid you want to carry before refilling, whether you prefer a tighter MTL pull or a looser draw, and whether your existing coils are compatible with the new tank. The table below should help point you in the right direction.

If you already own an Aspire device and just want a straight swap, matching the exact tank name is the safest bet. Buying the wrong Aspire Nautilus tank variant is one of the most common mistakes people make, since the coils across the Nautilus family are not all cross compatible, so always double check before you order.

 

Getting the Most Out of Your Tank

Coil resistance shapes your whole vaping experience. A higher resistance coil, such as the 1.8Ω BVC fitted in the K1 Plus, gives a tighter, more restricted draw with lower vapour, perfect for anyone who wants that classic cigarette-like pull. A lower resistance coil, like the 0.3Ω mesh option available for the Nautilus 3SR, opens things up for a looser, more airy draw with bigger clouds.

Always prime a new coil properly before your first vape. Add a few drops of e-liquid directly onto the coil, fill the tank fully, and let it sit for around five minutes before firing it. This simple step lets the wicking material soak up e-liquid properly, and skipping it is the number one reason new coils taste burnt straight out of the box.

If you are after a bigger tank than what is on this page, an Aspire Nautilus tank 10ml setup is worth searching for separately, since some Nautilus tanks can be paired with extended glass sections for extra capacity. It's a handy trick for heavier vapers who do not want to be refilling constantly throughout the day.
