InexPens Silicone Grease

InexPens Silicone Grease is used to seal the threads of your fountain pen when you perform an eyedropper conversion.

Another popular use for waterproof silicone grease is to lubricate piston-filled fountain pens and ink converters to keep them working smoothly.

If you’re looking to grease your piston seal pens or the threads on an eyedropper conversion, our waterproof silicone grease can be useful to you.

Why Use An Eyedropper Pen?

Eyedropper conversions are amazing fountain pens. They allow you to carry up to 3 or 4ml of ink, which is much more ink than any converter or cartridge allows you to.

When you convert a fountain pen into an eyedropper, you use the entire barrel as an ink reservoir, so there’s not any other solution that allows you to carry this much ink in your pen.


Piston And Converters Lubrication

If your piston filled fountain pen or your ink converters require too much effort to fill, it might be time to lubricate them with waterproof silicone grease. Just by using a little quantity of silicone grease, they work as new once again.


How To Use Silicone Grease?

You can simply use a small stick to get the silicone grease in the threads and then use your fingers or a glove to spread it on the threads.


Long Lasting Jar

InexPens Silicone Grease is waterproof and one single unit lasts for years. Even if you convert plenty of fountain pens to eyedroppers, each time you seal a thread you only need to use a drop of silicone grease. So, even a small jar should last you for years.
