StyloSeal Medium Consistency (Medium Stiffness) 100% Pure Silicone Sealant & Lubricant Grease for Fountain and Eyedropper Pen Applications

great for seal and lubrication of fountain pen piston after thorough wash

My Omas Milord Arco Celluloid fountain pen stopped drawing ink. After looking at several YouTube videos I decided to take it apart and repair it myself. It was a little difficult to remove the section, but I finally got it off. The plunger rod had become disconnected from the knob. I coated all of the connecting parts with a small amount of the silicon grease, and the piston rod, and reassembled the pen, making sure that the knob was attached to piston rod. Everything went back together smoothly. I filled the pen and it had no leaks. This product works as advertised.

Keeps the fountain pen ink where it needs to stay. It does stick to the lid, so be careful when opening

I compared this to the Danco silicone grease from lowes/home depot, this stuff is far more slick but while keeping that thicker viscosity which is perfect for sealing and smoothness. The danco grease is almost sticky in a sense where as this is not. Highly recommend.

This vendor packaged the silicone grease perfectly for shipment. It was sealed in a plastic bag to ensure a pristine product. Would buy again!

Thick workable grease

Works well. I used it on the Pilot Petit to convert to eye dropper. No issues, no leaks.

This will last forever! Works well to seal fountain pens.
