A drip tip, also called a vape mouthpiece, is the part of a vape tank or atomizer that you inhale through. Many vapers use the terms drip tip, tip and mouthpiece interchangeably, but the important part is knowing which size and fit your device uses.
Most modern vape tanks with removable mouthpieces use either a 510 drip tip or an 810 drip tip. Some devices use a proprietary mouthpiece, which means only a specific brand or model will fit properly. This guide explains the difference between 510 and 810 drip tips, how to measure your vape mouthpiece, and how to find the right replacement.
When people first start vaping, the mouthpiece is often overlooked. After a while, that changes. The shape, width, length and material of a drip tip can affect comfort, airflow, warmth and flavour.
As vaping evolved, mouthpiece designs also changed. Early tanks often used built-in or proprietary mouthpieces, but the rise of the RBA market helped popularize removable drip tips in different shapes and sizes. That is also where the term drip tip became widely used.
The main difference between a 510 drip tip and an 810 drip tip is the base diameter and airflow.
Many flavour-focused users prefer 510 drip tips because the narrower pathway can create a more concentrated vapour stream. Wider 810 drip tips are often chosen for increased airflow and a looser inhale.
Shorter mouthpieces can produce a warmer vape, while longer mouthpieces may cool the vapour slightly before it reaches your lips. The best option depends on your device and personal preference.
Advanced users, especially those using RDAs and rebuildable atomizers, helped drive the popularity of removable drip tips. Many early setups used 510 mouthpieces, which offered a removable, replaceable option with a narrower opening.
The term “drip tip” came from the ability to drip e-liquid directly through the mouthpiece and onto the wick without removing the top cap. As tanks and atomizers evolved, wider airflow setups became more popular, which helped establish the 810 drip tip as another common standard.
The easiest way to identify the correct vape mouthpiece is to measure the base of the drip tip, or the opening on the tank where the drip tip fits.
Do not include the O-rings in your measurement.
In imperial measurements, that is roughly:
If your measurement does not match either of those sizes, your device likely uses a proprietary mouthpiece.
A proprietary mouthpiece is a vape tip designed specifically for one tank or one product line. It does not follow the standard 510 or 810 size, which can make replacement options more limited.
If your tank uses a proprietary fit, it is important to confirm compatibility before ordering a replacement. Some devices will only accept the original manufacturer’s mouthpiece.
Sometimes, yes. Drip tip adapters can allow a 510 mouthpiece to fit into an 810 opening, or help adapt certain setups for a better fit.
Adapters are useful, but they do not solve every proprietary fit issue. Always check your device compatibility before ordering.
Choosing the right drip tip comes down to a few things:
Knowing the correct size is only the first step. The rest comes down to finding the right form, function, fit and finish for your vaping style.

A 510 drip tip is a narrower vape mouthpiece with a base diameter of about 8.5 mm. It is commonly used on many tanks and flavour-focused setups.
An 810 drip tip is a wider vape mouthpiece with a base diameter of about 12.5 mm. It is commonly used on sub-ohm tanks and setups designed for more airflow.
If your mouthpiece does not match standard 510 or 810 measurements, your device likely uses a proprietary fit designed for a specific tank or brand.
Often yes, with the correct adapter. Always check compatibility before buying.
