Silcone Plugs are now available for the ultem cartridge

by Eureka_Admin

There was a suggestion from a Eureka user.

"Could there be a method to plug the cartrige, so ink-filled cartridges can be sealed?"

This thought actually occurred to be as well, 

but to achieve this function mechanically, an additional thread must be machined along with a machined Lid.

This was more complicated than I realized.

 

A simple method was to use a silicone plug that will be compatible with the ultem cartridge.

and... here it is !

the black color will make ink stain less visible.

also since silicone is quite durable and chemically resistant to various ink types, this is a good solution.

now ultem cartridges can be filled with various ink colors, and safely be carried around.

 

* when installing / removing the silicone plug, you must rotate it to prevent sudden movement.

* A certain amount of it must be inserted to make sure it won't loosen. You will be able to feel the right amount of resistance and depth.
