Pilot converter (CON-70) not gripping section

[DavidD62]

I was very fortunate to find a used Namiki Impressions c. 1996 in emerald green today at a local brick and mortar. This pen accommodates the large Pilot CON-70 converter. I tried two different CON-70s, one of which was brand new in a factory sealed package. Neither grips the section securely. I inspected the section and don’t see anything broken (as can sometimes be the case). 
 

Does anybody have a repair suggestion for this problem?

 

I could return the pen because the store has a liberal return policy, but an emerald green Impressions is pretty rare. I have sent pens back to Pilot and I’m sure they could replace the section, but that will take months and probably cost $100+. If there is an easy fix, I’d love to find it first.

 

Thanks for reading, and for your suggestions!

Sorry thought the international adapter fit into Pilot pens but it was Platinum. Thanks hari

Check to see if the section has the cartridge piercer nipple. It can be easily identified when you see your known good pilot pen. This piercer nipple is a threaded part and sometimes unscrews and comes out along with the converter and can get lost. Just check if it’s there. The int cartridge adapters are found on the platinums.

Pilot cartridge/converter pens have a sort of crescent-shaped piercer. It is all there. I wasn’t aware these were threaded. On the Namiki Impressions, the nib and feed are friction fit and can be pulled out of the section pretty easily. The crescent-shaped bit remained attached to the section when I removed the nib and feed.

 

A friend suggested putting a thin strip of tape on the outside of the CON-70 to cause it to grip the inside of the metal threaded section part. This may work, but it feels like a kludge.

 

Are you saying there is an adapter that allows Platinum pens to use international standard cartridges? I did not know this.

Yes that seems to be true. People buy used ones that already contain the adapter and can't get the Platinum converter in.
