Aspire Nautilus X U-Tech Coils

Aspire Nautilus X U-Tech Coils

Each pack of Aspire Nautilus X U-Tech Coils holds 5 replacement coil heads for the Nautilus X tank. Two resistances are offered, 1.5ohm and 1.8ohm, and both are built around Kanthal wire. A pack contains one resistance only, so the choice is made at checkout.

A U-shaped chamber carries vapour past the coils twice before it reaches the mouthpiece, which suits a mouth-to-lung draw. The 1.5ohm coil is rated at 14-20W and the 1.8ohm coil at 12-16W. Each coil is changed by hand, so only the worn part is replaced.

What to Know About the Nautilus X U-Tech Coils

• 5 coils in every pack, all of one resistance
• 1.5ohm and 1.8ohm options
• 14-20W for the 1.5ohm coil and 12-16W for the 1.8ohm coil
• Kanthal wire inside a U-Tech chamber
• Fits the Nautilus X tank, not the PockeX

Features of Aspire Nautilus X U-Tech Coils

These points cover the chamber, the wire, both resistances and the pack size. The coils belong to the wider Vape Coils range sold for refillable tanks.

U-Tech Airflow Chamber

Air is taken in through the top airflow of the tank and guided through a U-shaped chamber inside the coil. Vapour is pulled past the Kanthal coils twice before it is inhaled, which is the idea behind U-Tech. The design is aimed at mouth-to-lung vaping, where flavour matters more than cloud size.

Kanthal Heating Wire

The heating element is made from Kanthal wire in both resistances. Kanthal is a resistance alloy that suits standard wattage vaping, and both coils are rated between 12W and 20W. The output of the battery or device fitted to the tank should therefore be kept inside that range.

1.5ohm Coil at 14-20W

The 1.5ohm coil is the looser of the two, though the draw is still mouth-to-lung. It is rated at 14-20W. Nautilus X 1.5ohm coils are the pick when a little more vapour is wanted. Output is best raised in small steps.

1.8ohm Coil at 12-16W

A more restricted draw is given by the 1.8ohm coil, rated at 12-16W. Because it runs at a lower wattage, the same battery charge lasts longer between top-ups. A tighter, cigarette-style pull is what this pack is chosen for.

Pack of 5 Coils

Every pack holds 5 coils of a single resistance, so a spare is always to hand. A coil is due for replacement when flavour fades, the vapour tastes burnt or the tank begins to gurgle. Only the coil needs to be swapped, and the tank stays in place.

Nautilus X U-Tech Coil Resistance Options

The two coils share the same chamber and wire, so the choice comes down to draw and wattage. Nautilus X coils in 1.5ohm suit a device set between 14W and 20W.

The 1.8ohm coil works best between 12W and 16W. Setting the device above the rated range for either coil is not recommended, since a burnt taste is the usual result.

How to Swap the Nautilus X U-Tech Coils

The steps below apply to both resistances.

Step 1: Remove the tank from the battery and empty any e-liquid that is left inside it.

Step 2: Twist the spent coil out of the tank and set it aside.

Step 3: Prime the fresh coil by letting several drops of liquid fall onto its wicking openings, without flooding it.

Step 4: Thread the new coil into place until it sits firmly, then top-fill the tank with a bottle from the E-Liquids range.

Step 5: Stand the tank upright and wait a moment, so the liquid soaks into the coil.

Step 6: Reattach the tank to the battery, begin with the lowest wattage rated for that resistance, then raise output gradually.

What's in the Nautilus X U-Tech Coils Pack

Each pack contains the coils and nothing else.

• 5 x Aspire Nautilus X U-Tech coils, all of the resistance chosen

The Nautilus X tank, a battery and e-liquid are not included.

Devices Compatible With the Nautilus X U-Tech Coils

The Aspire Nautilus X tank is the device these coils are made for. Tanks of this type are gathered under Vape Tanks for anyone who still needs one, and the MTL Tanks range covers the mouth-to-lung style.

The PockeX also uses U-Tech coils, but the two coil types cannot be swapped between the PockeX and the Nautilus X. Coils sold for other Nautilus tanks, the BVC range and the Nautilus Mini carry their own part numbers, so the name on the tank should be checked before ordering.

About Aspire and the U-Tech Coil Platform

Aspire U-Tech coils are used in more than one product line. The same U-shaped chamber is found inside the Nautilus X coil and inside the PockeX pen system, although each keeps its own coil size. Aspire's Nautilus family of tanks has grown over several versions, and replacement coils are matched to the tank rather than shared between them.

That is why a coil for one version should not be assumed to suit another. More tanks, kits and parts from the brand are listed under Aspire Vapes.

Stock Up on the Nautilus X U-Tech Coils

One pack of each resistance makes it simple to compare the 1.5ohm and 1.8ohm coils on the same tank, and spare Nautilus X coil heads mean a worn coil never stops the vape.

Baskets above £40 qualify for free delivery, and same-day dispatch applies to Pirate Vapes orders placed before 3:30pm from Monday to Friday. A second pack of either coil suits the Multi-Buy Vapes range.

Conclusion

The Nautilus X U-Tech Coils suit anyone running a Nautilus X tank who wants a mouth-to-lung coil in either 1.5ohm or 1.8ohm, with a wattage range printed for each. Coil heads for other tanks are kept separate, so this pack is for the Nautilus X only.

Batteries and other spares are found in Vape Accessories, while everything else in the range can be reached from the Pirate Vapes homepage. Coils are hardware, and all orders are for adults aged 18 and over.

FAQs

Which tank do the Aspire Nautilus X U-Tech Coils fit?

The coils are made for the Aspire Nautilus X tank. They are not interchangeable with the PockeX coils, even though both use U-Tech.

How many coils come in a pack of Nautilus X U-Tech Coils?

A pack holds 5 coils of one resistance. The 1.5ohm and 1.8ohm coils are sold as separate packs.

What wattage suits the Nautilus X 1.5ohm coil?

The 1.5ohm coil is rated at 14-20W, so the device should be set inside that range. Starting near 14W and raising the output slowly gives the best chance of avoiding a burnt taste.

What is the difference between the Nautilus X 1.8ohm and 1.5ohm coils?

The 1.8ohm coil is rated at 12-16W and gives a more restricted draw, while the 1.5ohm coil is rated at 14-20W and is slightly looser. Both are built with Kanthal wire and the same U-Tech chamber.

Can Nautilus X coils be used on the Aspire PockeX?

The PockeX needs its own coils, because the two coil types cannot be swapped even though both use U-Tech. These coils are for the Nautilus X tank only.

How often should the Nautilus X U-Tech Coils be replaced?

There is no fixed interval, because the life of a coil depends on the wattage and the e-liquid used. Fading flavour, a burnt taste or gurgling from the tank are the usual signs that a fresh coil is needed.
