Repair Stipula Nettuno Idra?

[markh]

I have a Stipula Nettuno Idra, which is a sleeve filler. This is a modern, not vintage pen.

 

In this case, there is a special "converter" with threads at both ends, and a sac with pressure bar in the middle . The sac had gotten old and crunchy.

 

There doesn't appear any obvious way to take the internal unit apart to replace the sac.

 

Anyone know how to repair, or where to get it repaired?? I would rather do it myself - resacing a pen is within my skill. But it almost looks as if this is press fitted in a way that can't come apart easily.

 

Thanks for any help,

We're faced with the same challenge -- how to re-sac the threaded filling unit. It looks like there is a plastic piece inside the sac that sandwiches the lip of the sac to the filling unit.

 

We've got it apart and here's a photo:

Additionally, there's an o-ring that fits up against the base of the plastic piece and the edge of the sac.

Hi Teri,

 

what did you eventually figure out for removing/replacing the sac? I have an Idra that needs the same repair.
