How to Fill Various Types of Fountain Pens

If you’re after that timeless elegance, the smooth writing experience, or simply a more personal touch in your writing, chances are you own a fountain pen. With a plethora of fountain pen types, each boasting its own ink replenishment techniques, the most common methods involve either cartridges or pneumatic systems to draw ink into the barrel, facilitated by plungers or pumps. Even if your pen doesn’t neatly fit into these categories, you can likely apply the same fundamental principles to refill it. If you’re unsure, especially with older or rarer pens, seek assistance from a fountain pen retailer who can identify and refill your particular model.

Step-by-Step Guide

Identifying and Opening Your Pen

Remove the cap. The cap covers the pen’s “grip section,” where you hold it, and the “nib,” the tip where ink emerges.

Unscrew the barrel. The barrel encases the pen's body, holding the ink reservoir. This step is typical for most modern pens. However, older or rarer models might feature self-filling mechanisms, eliminating the need to unscrew the barrel.

Instead of a barrel cover, integrated piston or button systems may feature a “blind cap” over the screw knob or button.

Identify your filling method. If you're uncertain about which method to use, inspect the interior of your pen. Chances are, you'll find either a plastic cartridge, a piston converter system with a plunger, or a squeeze-filler converter system equipped with a long button on the pen's side.

Refilling a Cartridge Pen

Select the appropriate cartridge size. While some pens utilize standard-sized cartridges (small or large), others may require proprietary brands that don't accommodate standardized sizes.

Extract the cartridge, if one is inserted. Removing the cartridge is straightforward: simply pull it straight out from the grip section.

If a converter is installed, remove it. For pens equipped with a piston or squeeze converter, simply pull it straight out from the grip section, mimicking the process of removing a cartridge.

Install a new cartridge. Insert the stopper end into the grip section, applying firm pressure until you hear a click indicating the stopper has punctured. This action initiates the ink flow into the pen.

Reattach the barrel. Screw the barrel securely back onto the pen's body.

Store the pen vertically. Hold the pen with the nib facing downwards to allow the nib to saturate. Use a small glass or another vertical stand to keep the pen upright. It may take a couple of hours for the nib to fully saturate and enable smooth writing.

Filling a Piston or Squeeze Converter-Equipped Pen

If a cartridge is inserted, remove it. The converter will take the place of the cartridge. To remove the cartridge, simply pull it straight out from the grip section.

Insert the converter if it's not already in place. Slide the converter straight into the grip section. Some converters may have small “lugs” on the side that need to be aligned with open slots.

Immerse the nib in ink. Completely submerge the nib, up to the grip section, ensuring that the vent hole is below the ink level.

Squeeze and release the converter. If you're using a squeeze converter, compress the side of the pen until ink bubbles form. Gradually release pressure, then slowly release the converter to allow suction to draw ink into the pen.

Squeeze and release the converter again. Repeat until bubbles cease to appear in the ink bottle, indicating the pen is full.

Rotate the converter to operate the piston. For piston converters, twist the end of the pen counterclockwise to move the internal plunger up or down. Then twist in the opposite direction to draw ink into the tube.

You may need to operate the piston several times to completely fill the pen with ink.
Eliminate air pockets. If the converter was completely empty at the start, you might encounter difficulty filling it entirely due to an air pocket. To remove this, twist the plunger counterclockwise to expel all ink along with the air, then refill.
Expel a few drops of ink. Withdraw the nib from the ink, and twist the piston counterclockwise until a few drops of ink emerge. This primes the pen for writing.

Wipe off any excess ink from the nib. Use a cloth or paper towel to eliminate any remaining ink from the nib.

Reattach the barrel. Screw the barrel back onto the pen's body.

Filling an Eyedropper Pen

Remove and unscrew the barrel. Unlike cartridge or converter pens, the barrel doesn't house a cartridge or converter but serves as an ink reservoir itself.

Clean the barrel. If you're using a new pen or switching ink colors, cleanse the barrel using a cotton swab.

Lubricate the threads. To prevent ink leakage, it's essential to establish a watertight seal where the barrel connects to the grip section. Apply silicone grease to the threads. Screw the barrel on, then unscrew it to evenly distribute the grease between the threads.

Refill the pen using an eyedropper. Submerge the eyedropper into the ink bottle, drawing ink into it. Insert the tip of the eyedropper into the upright barrel and release the ink, filling the barrel. Ensure the ink level reaches the bottom of the threads.

You may also utilize a syringe instead of an eyedropper.

Partially screw the grip section into the barrel. Position the grip section onto the barrel and commence screwing it in place.

Rotate the pen to an upright position (nib downward) and complete the screwing process. This action will prompt a few drops to emerge from the feed, preparing the pen for writing.

Remove any excess ink from the nib. Utilize a cloth or paper towel to eliminate any remaining ink from the nib.

How to Fill Various Types of Fountain Pens

Refill a vacuum filler pen. Inside a vacuum filler pen, there's a plunger that remains within the barrel. Removing the knob allows the plunger to move freely up and down. Pull the plunger up to create a vacuum inside the pen, then push it back down.

As the plunger reaches the wider, flared section of the pen, it will break the vacuum, drawing ink into the barrel.

Replenish a lever pen. A lever pen features a lever in the middle to compress a sac. To fill the pen, lift the lever first, then immerse the nib in ink. Push the lever back into position and wait briefly. Finally, snap the lever back into place.

You may need to repeat this process a couple of times until the pen is fully filled.

Top up a button filler pen. A button filler pen employs a button to compress a sac, creating suction to draw ink into the pen. To fill it, remove the blind cap at the end of the pen. Press and hold the button to compress the sac. Dip the nib into the ink, then release the button to fill the pen.

Handy Tips

Many cartridge-style pens can store a spare cartridge inside the barrel.
Some cartridge pens can be converted into eyedropper pens, offering increased ink capacity and a wider range of colors. Ensure the barrel is watertight and refer to a tutorial before attempting conversion.
Bottled ink offers a broader range of colors. With a cartridge pen, you can refill empty cartridges using a syringe, granting access to rare hues.

Cautions

Always clean your nib!
Avoid forcing a stuck piston. If a piston-filler pen has been stored with ink for a prolonged period, the piston may become stuck. Excessive force can damage the piston mechanism.

Essentials
