How to Transfer Oil Between Carts

Are you looking to transfer oil between carts? Whether you want to consolidate your oil into a single cartridge or simply move it from one cart to another, there are several methods you can use. In this article, we will explore various techniques for transferring oil between carts, ensuring a seamless process without any spills or waste. So let’s dive in and discover the best methods for transferring oil effectively.

How to Transfer Oil Between Carts

Transferring oil between carts can be a useful technique for various reasons. It allows you to consolidate oil from multiple carts into a single one, mix different oil strains, or simply move oil to a cartridge with better functionality. To help you accomplish this task efficiently, we have outlined several methods below.

1. Pouring the Desired Amount of Oil

One straightforward method of transferring oil is by pouring the desired amount directly. Begin by turning one cartridge upside down so that the mouthpiece is facing up. Use your fingers to remove the rubber tip at the end of the cartridge. Depending on how much oil you want to transfer, you can pour the desired amount of oil into your mouth or another cartridge.

2. Using a Clean Rag to Wipe Out the Inside Cartridge

For a more controlled transfer, you can utilize a clean rag and a straw. Start by removing the rubber tip from the cartridge. Insert a straw into the opening, and with your mouth on the other end of the straw, quickly remove the cartridge from your mouth. Then, insert it into another cartridge that already contains oil. Wipe the inside of the first cartridge with a clean rag to collect any remaining oil.

3. Using a Metal Rod or Pen

If you prefer a tool-assisted approach, you can use a metal rod or a pen. First, remove the rubber tip from one cartridge. Take the pen or rod and push down the other cartridge’s tip until it is roughly one centimeter deep. Remove the pen or metal rod and position the cartridge for oil transfer. Insert a syringe or any other suitable tool to pour the oil from one cartridge into another.

4. Using a Syringe

One of the most common and precise methods for oil transfer is using a syringe. This method requires a syringe with a blunt tip, which you can purchase online or at a local pharmacy. Simply extract the oil from one cartridge using the syringe and then inject it into another cartridge. Make sure both cartridges have compatible threading to avoid any leaks or damage.

5. Using Hot Water

Hot water can be a helpful tool for a direct transfer without using a syringe. Hold the capped cartridge under hot water from the faucet for a minute or two, allowing the oil to heat up. This process makes the oil less viscous and easier to pour. Once heated, pour the oil from one cart into another while being cautious not to spill any.

6. Biting Down on the Cartridge

In a pinch, when you have no other tools available, you can transfer oil by biting down on the cartridge. It is essential to exercise caution when using this method and ensure you protect your teeth from the metal. Having a cloth or some other protective barrier can help prevent any discomfort or damage.

Precautions and Tips

When transferring oil between carts, it is crucial to keep the following precautions in mind:

  • Take care not to spill or waste any oil during the transfer process.
  • Ensure that the carts you are using are compatible and have the same threading to avoid leaks or damage.
  • Clean any spills or excess oil promptly to maintain cleanliness and prevent any potential hazards.


Transferring oil between carts can be a simple process if you follow the appropriate methods and precautions. Whether you choose to pour the oil, use tools like syringes or metal rods, or utilize hot water, there are various options available to suit your needs. By employing these techniques, you can efficiently transfer oil between cartridges without any hassle or wastage.


can I transfer oil between carts with different threading?

Ideally, it is recommended to use carts with the same threading to ensure compatibility and prevent leaks. However, if you need to transfer oil between carts with different threading, you may consider using alternative methods like pouring or using a syringe with a compatible attachment.

How can I prevent spills or waste during the oil transfer?

To avoid spills or waste, ensure a steady hand while pouring the oil and maintain control over the transfer process. Using tools like syringes or clean rags can help you have a more controlled and precise transfer.

Is it necessary to heat the oil before transferring it?

Heating the oil with hot water can reduce its viscosity, making it easier to transfer. However, this step is optional and depends on your specific requirements. You can transfer oil without heating if you find it more convenient.

Can I reuse cartridges after transferring oil?

Yes, you can reuse cartridges after transferring oil between them. Ensure that the cartridges are clean and free from any residues before using them again.

Where can I purchase syringes for oil transfer?

Syringes with blunt tips suitable for oil transfer can be purchased online from various retailers or at your local pharmacy. Ensure that the syringe you choose is appropriate for your specific needs.
