OBS Cube Replacement Coils

1.4-ohm NX mesh. Optimized for low-wattage Mouth-to-Lung (MTL) Vaping. The OBS Cube replacement coils featured here are the NX mesh variant, engineered to deliver a tighter, cigarette-like draw with exceptional flavor clarity.

Featuring premium mesh wicking paired with Japanese organic cotton inside a robust stainless steel frame, this combination provides a smooth throat hit, reliable longevity, and pristine taste. Five coils per pack at Pirate Vapes. Threads securely into the base of the OBS Cube Tank. Perfect for High-Nicotine E-Liquids and nic salts. TPD compliant. Over 18s only. 

Why vapers choose the OBS Cube Replacement Coils:

• Mesh heating element across a balanced surface area means even heat distribution with zero hot spots. The NX mesh strip activates instantly at low power, producing a richer flavor profile and a smoother throat hit than standard round-wire MTL coils.

• Japanese organic cotton wicking absorbs e-liquid efficiently and delivers clean flavor from the very first puff. The wicking ports on the stainless steel frame are perfectly sized to keep pace with structured MTL draws, preventing dry hits when using standard 50/50 e-liquids or nic salts.

• Cross-compatible with SMOK TFV8 Baby coils. If you ever want to try a different coil style in your OBS Cube Tank, TFV8 Baby coils drop straight in. This gives you access to one of the widest coil ranges on the market without buying a new tank. Not every OBS Cube owner knows this, but it is a genuine bonus.

• The stainless steel frame retains heat efficiently and protects the mesh and cotton from physical damage. The frame has multiple wicking ports cut into it so e-liquid flows to the cotton from several angles rather than relying on a single channel. This reduces the chance of localised dry spots during heavy use.

• A focused Mouth-to-Lung alternative. Instead of trying to satisfy every vaping style with one generic design, OBS tuned the mesh gauge, cotton density, and port sizing of the NX Mesh specifically for low-wattage, higher-nicotine vaping. The result is a consistent, reliable MTL experience that doesn't compromise on flavor clarity. 

OBS Cube Replacement Coils Features

NX Mesh Heating Element

The NX Mesh coil uses a micro-mesh strip optimized for lower power delivery. It heats uniformly and instantly at lower wattages, providing pristine flavor clarity and a stable, smooth throat hit throughout the entire duration of your draw without spiking or burning. 

100% Japanese Organic Cotton Wicking

The cotton inside each NX Mesh coil is premium Japanese organic material. It absorbs thinner 50/50 e-liquids and nic salts quickly, delivering clean, uncompromised flavor from the very first draw with zero break-in taste. 

Stainless Steel Frame with Multi-Port Design

The outer frame of each coil is stainless steel with multiple wicking ports cut around its circumference. These ports let e-liquid reach the cotton from several directions simultaneously, which prevents the single-point dry spots that simpler coil frames create. The steel also retains heat efficiently, helping the mesh maintain consistent temperature.

Threaded Base Installation

The NX Mesh coil screws directly into the base deck of the OBS Cube Tank. Simply unscrew the old coil counter-clockwise, line up the threads of your freshly primed replacement, and twist it in clockwise until it is firmly finger-tight. The secure threaded connection ensures an airtight seal and eliminates any risk of shifting or leaking during daily use. 

SMOK TFV8 Baby Coil Cross-Compatibility

The OBS Cube Tank accepts SMOK TFV8 Baby coils in addition to its own NX mesh coil. That cross-compatibility opens up a wider range of resistances and coil styles than OBS offers on its own. If you want to experiment with different wattages or draw styles without changing your tank, Baby coils give you that option.

OBS Cube Replacement Coils Options

Unlike the sub-ohm M1 coils, the NX Mesh is built specifically for a tight MTL draw. It uses a fine mesh structure to deliver instant heating at low wattages, giving you a smooth throat hit and pristine flavour clarity.

If you want to explore other resistances or vaping styles in the same tank, the cross-compatibility with SMOK TFV8 Baby coils gives you access to additional options.

How to Set Up the OBS Cube Replacement Coils | Pack Of 5

1. Unscrew the tank base. Hold the OBS Cube Tank and twist the base section anti-clockwise until it separates from the glass. The old coil stays in the base.

2. Remove the old coil. Unscrew and remove the used coil from the base. It may need a firm push if residue has built up. Discard it.

3. Prime the new coil. Drop three to four drops of e-liquid directly onto the cotton visible through the wicking ports on the side of the new NX coil. This pre-saturates the Japanese organic cotton before installation.

4. Put the new coil in. Take your freshly primed coil, seat it into the base threads, and screw it in clockwise until it's firmly finger-tight. Make sure the threads line up straight to avoid any leaking.

5. Reassemble. Screw the base back onto the glass section of the tank. Finger-tight.

6. Fill. Unscrew the top cap of the OBS Cube Tank and pour 50/50 VG/PG E-Liquid or nic salts down the inside wall of the glass. Avoid the central airflow chimney. Fill to the line.

7. Wait. Let the tank sit for five to ten minutes so the mesh coil and cotton fully absorb the liquid. Mesh coils have more surface area than wire coils, so they need a longer prime.

8. Vape. Attach the tank to your OBS Cube mod, set the wattage to low power (10-15W), and fire.

What's in the OBS Cube Replacement Coils | Pack Of 5 Box

Five OBS NX Mesh coils at 1.4 ohm. Each coil is individually wrapped. No tank, no mod, no e-liquid included. These are replacement coils only. You need an OBS Cube Tank (from the OBS Cube, Cube X, or Cube FP starter kit) to use them.

Built for the OBS Cube Tank Family

The NX mesh coil is designed for the OBS Cube Tank and fits every variant of the OBS Cube kit range. The SMOK TFV8 Baby coil cross-compatibility also gives you access to a broader coil selection.

Works with: The OBS Cube Tank (original), the OBS Cube X Tank, and the OBS Cube FP Tank. All three use the same coil base fitting. The NX coil drops into any of them. Additionally, SMOK TFV8 Baby coils fit the OBS Cube Tank, which opens up Baby Mesh, Baby Strip, and other Baby-series coil options as alternatives.

Does not fit: Other OBS tanks outside the Cube family (different coil systems), GeekVape Zeus tanks, VooPoo PnP pods, or any pod-style device. The OBS Cube Tank is a 510-threaded sub-ohm tank, not a pod cartridge.

About OBS

OBS (Original Best Solution) has been producing vape hardware since 2013. They built their reputation on the Engine RTA series before launching the Cube range of compact sub-ohm starter kits. The OBS Cube was designed as a simple, high-performance starter kit with a single-coil mesh system and a built-in battery mod.

The Cube platform expanded its capabilities with the NX Mesh series, fine-tuning the mesh density and wicking properties specifically to adapt the Cube Tank's internal chamber for an outstanding, high-resistance MTL experience. Browse the full OBS Vapes collection at Pirate Vapes.

Five coils per pack. With typical low-wattage MTL use, a single pack comfortably covers weeks of daily vaping. Because the NX Mesh runs at lower power, it is inherently gentler on both your battery and your wicking material. If this is your daily go-to setup, grabbing two packs means you are set for months.

At Pirate Vapes, we pack coils padded and sealed because mesh structures are delicate and deserve to arrive in pristine condition. Every product is TPD compliant and sold through age-verified checkout. Same-day dispatch before 4pm. Free Pirate Post over £25. 

Conclusion

The OBS Cube NX Mesh coil delivers a premium, tight Mouth-to-Lung vape with exceptional flavor definition. By optimizing the mesh structure specifically for a 1.4-ohm resistance, OBS created a reliable option for vapers who prefer nic salts or standard 50/50 e-liquids over massive sub-ohm clouds.

The cross-compatibility with SMOK TFV8 Baby coils gives you room to experiment if you want alternatives. And at five coils per pack, a single box covers weeks of daily vaping. If you run an OBS Cube kit, these are the coils it needs. Grab a pack from Pirate Vapes and browse our Replacement Coils collection and OBS vapes range.

FAQs

Is there a higher or lower resistance option? 

Yes. While the Cube tank originally launched with low-resistance sub-ohm coils, Pirate Vapes supplies the NX Mesh 1.4 Ohm coil. It provides a fantastic higher-resistance option for anyone looking for a classic Mouth-to-Lung experience.

What wattage should I run it at? 

The 1.4-ohm NX Mesh is a dedicated low-wattage MTL coil. You should run it at low power (typically between 10-15W depending on your device's preferences) to ensure optimal flavor delivery and prevent the cotton from burning. 

Can I use nic salts with this coil? 

Absolutely. For the 1.4-ohm NX Mesh, nic salts and higher-nicotine e-liquids are exactly what you should use. The lower wattage and tighter draw ensure a smooth, satisfying throat hit without delivering too much nicotine at once. Avoid high-VG liquids here, as they might be too thick for the smaller wicking ports. 

Do SMOK Baby coils really fit? 

Yes. The OBS Cube Tank is cross-compatible with SMOK TFV8 Baby coils. This is confirmed by multiple retailers and user testing. It gives you access to additional coil options without changing your tank.

How long does each coil last? 

One to two weeks of daily MTL use for most vapers. Sweet dessert e-liquids with heavy artificial sweeteners will naturally shorten that window, while simple fruit and menthol flavors are much gentler on the cotton. Keeping your device within the recommended low-wattage range (10-15W) will maximize the lifespan of the coil.

What VG ratio should I use? 

50/50 VG/PG ratios or high-PG blends work best. This coil is designed specifically for thinner e-liquids, like classic freebase nicotine and nic salts. Thicker 70/30 high-VG liquids should be avoided, as they can struggle to wick through the smaller ports of an MTL coil.
