810 drip tip guide, sizes, adapters and materials explained

Par The Vape Conseils desk15 October 20267 min de lecture

Swapping a mouthpiece looks trivial, right up to the moment the 810 drip tip you ordered rattles in the tank or refuses to go in at all. They come in resin, Delrin or Ultem, and their looks often take up more room than their measurements in product descriptions. The number 810 does not tell the whole story, and the adapter meant to solve the problem comes in two opposite versions. Before you buy, it pays to know what to measure and what you are after.

The 810 drip tip, a wide-bore mouthpiece for airy vaping

An 810 drip tip is a wide-bore mouthpiece made for sub-ohm tanks and rebuildable atomisers (RTA, RDA) designed for direct-to-lung vaping, where vapour goes straight to the lungs. Retailers give an outer diameter of about 12.5 mm at the base, against about 8.5 mm for the 510 format.

That wider opening lets a bigger flow of vapour through. Tanks built for a tight mouth-to-lung (MTL) draw tend to use the 510 format.

In the UK, refillable nicotine tanks are capped at 2 ml, so the sub-ohm tanks that take these tips are sold in 2 ml versions, while the mouthpiece itself is the same whatever the tank size.

Measuring the base before buying an 810 drip tip

The first mistake is trusting the format name alone. Published figures are close but not identical, and how well a tip sits also depends on its seals.

The figures retailers publish

One retailer quotes 12.5 mm for the outer diameter of an 810 base, another 12.6 mm. An adapter designed to hold an 810 tip lists a 13 mm socket. Common models stand between 15 and 25 mm tall, according to one retailer.

The inner diameter varies from model to model and is hardly ever given. Yet it is the inner bore that sets the airflow and the feel in the mouth.

The safest route is to measure for yourself. A pair of callipers across the original tip, at the level of its seals, gives the useful diameter in seconds, and the same reading taken inside the tank opening confirms the space available. Note the height of the original tip too, which matters when the top cap or fill button sits right below it.

What the O-rings do

On many models, one or two O-rings seal the joint and hold the tip in the tank. A loose tip can be down to a worn or missing O-ring rather than the wrong format. Some models screw in instead, which gives a firmer hold on an RTA or RDA.

Bore, height and shape, how the draw changes

A narrow tip generally gives a tighter vape, a wide one a more open, airy draw. Diameter, height, material and shape also affect the heat you feel and comfort on the lips.

One retailer advises against long, thin tips on a sub-ohm tank, because the condensation they encourage can lead to leaks. Short, wide tips, on the other hand, suit heavy vapour production.

A tip with a tapered bore tends to concentrate flavour, according to another retailer. An 810 drip tip is therefore more than a cosmetic extra, as it genuinely changes how the vapour reaches your mouth.

Adapters, one way or the other

The word adapter covers two parts that do opposite jobs. Picking the wrong direction means buying a part that will not fit your kit.

The 810 to 510 adapter

It sits in the 810 opening of a tank and lets you fit a 510 tip, for instance to keep a slim mouthpiece you like. The listing we read describes an acrylic model.

The 510 to 810 adapter

This one works the other way. Fitted to a 510 opening, it takes an 810 tip. One Ultem model lists an 8.6 mm connection, a 13 mm socket and 6.5 mm of usable height. Buyers do report that the tip can come loose or sit poorly depending on the hardware.

Choosing the material of your 810 drip tip

Material decides the heat you feel, how tough the tip is and how easy it is to clean. Retailers broadly agree on the main points.

Resin, cured under UV light, comes in a huge range of patterns and insulates well against heat, but it does not cope with drops. Delrin (POM) stands up to knocks, liquids and heat, which makes it a safe choice on a sub-ohm tank.

Ultem (PEI), golden and translucent, handles heat very well and stays comfortable in the mouth, but it also dislikes being dropped. Teflon (PTFE) insulates well and turns up on higher-end hardware. Some tips carry a Teflon or PEEK insert to limit heat transfer, and acrylic remains the material of entry-level models.

Spitback and anti-spitback designs

On a high-wattage atomiser, small drops of hot liquid can reach your lips. Some 810 tips include an anti-spitback design, such as an internal spiral that catches those drops before they leave the tip.

This kind of tip mainly suits rebuildable atomisers and high-wattage setups. It changes the vapour path slightly, which can alter the feel of the draw.

Keeping the tip clean

One retailer recommends cleaning the mouthpiece regularly, especially if it travels in a pocket or a bag. A rinse in warm water followed by thorough drying is usually enough, with the O-rings removed to reach their grooves.

Check the O-rings at every clean as well. A split ring lets the tip wobble and opens the door to small leaks. For coil-related faults, our guide to the check atomiser warning covers the checks to run on each type of kit.

FAQ

Five practical questions before buying or replacing a mouthpiece.

Does an 810 drip tip fit the TFV12? Yes, several retailers list their 810 tips as compatible with the TFV8 and TFV12 tanks. Still, check the opening on your own tank before buying.

Is an 810 drip tip suitable for a tight draw? Rarely. The format is designed for direct-to-lung vaping, and tanks with a tight draw tend to use 510. An 810 tip with a narrow inner bore tightens the draw slightly, without changing the tank's own airflow.

Why does my mouthpiece get hot at high wattage? Material plays a big part. Resin, Delrin, Ultem or a Teflon insert limit the heat that reaches your lips, while a short tip on a very powerful atomiser lets warmer vapour through.

What should I do if the tip feels loose? Start with the O-rings, the usual culprits. If they are in good shape, compare the diameter of the tip with the tank opening, since a few tenths of a millimetre are enough to create play.

Can I keep a 510 tip on an 810 tank? Yes, with an 810 to 510 adapter in the opening. It lets you keep a slim mouthpiece, with a tighter draw than a wide-bore tip in return.

Choosing the right 810 drip tip

The right 810 drip tip is chosen by the measurement of the tank opening, along with the material and the draw you want. Product listings do not always give those figures, and adapters come in two opposite directions.

A heat-resistant material, sound O-rings and regular cleaning are enough to get the best from it. To place this accessory in a complete setup, our Vaporesso Target 100 guide looks at a kit built for airy vaping, and choosing an 810 drip tip works best when you think about the whole kit.
