Hello,

 

I tried looking around for a related topic, but couldn't find one that answered my question...If I store a vintage pen, after I clean it thoroughly of course, and it has a rubber sac (Eversharp Skyline, Esterbrook J etc) or a rubber diaphragm (Parker Vacumatic, "51" Vac), is there any danger that the rubber will ossify and crumble after a period of time spent in storage? Thank you.

 

Cheers,

Dragos

Yes and no.  Yes because eventually all of these rubber parts will dry up, rot or melt. No because this is a lengthy process and if you have had them replaced in recent years you should have many (10-30) years of service before they quit performing their intended function.

That is very nice to know! They have indeed been restored quite recently, but I've always been somewhat afraid to store them. Thank you for the answer.

The latex will go bad weather they are in storage or in use.
