Hard Rubber Crack Repair


Nestorvass

Recommended Posts

I recently purchased a Parker Duofold Jr from a seller at the flea market. The pen was in good condition. However I did notice that the hard rubber cap had a few thin cracks all over its lip. Is there a way to repair them by chemically welding them or are then any other methods that will give a solution to my problem? Note that the previous owner thought it would be a good idea to super glue the crack which of course didn't work due to the oxidization of the hard rubber. I placed some photos below so you can see the cracks.

The short answer is no.

What about the long?

 

I'm a bit pressed for time or I'd do the heavy lifting. It is a common subject when speaking about true vintage pens (going back on the eariy part of the last century). Simply doing searches here on FPN would return many threads discussing this; internet searches would fill out the picture either further. The topic has been covered many times just here on FPN, and the mods and members of the repair forum have offered many thoughts.

 

The issue is that the original material - hard rubber - does not respond to solvent welding and other tactics commonly used in repairing celluloid, acrylic and other pen materials. On top of that is both the commonality of the lip cracks (a thin part of the pen) along with the fact that it would be cosmetic at best, and you could never post the cap again (which is where the caps usually spring from).

 

I'd urge you to spend a little time doing searches on "repairing hard rubber pens" or something similar. I'm not saying that someone might not come up with something, newer bonding agents my pop up that work, but in general, the consensus has been that this is one of the areas of pen manufacture and history that is hard to restore. The good part is that the pen in question can be somewhat commonly found and a replacement cap won't be particularly hard to source (pen shows, vendors (I'd try Five Star Pens to start), eBay).

 

Hope that's long enough. :D

This is a question that comes up rather frequently, and Jon's answer is correct. I had a rather long and detailed answer to this a couple of months ago. If you take some time reading through this thread, and post #10 in particular, you may find your question to be answered in sufficient detail.

I thank the both of you for your answers :) . To be honest I was almost certain that there isn't a way to repair this. The good thing is that due to the ring thats on the cap I can post my pen without making the crack any worse, so repairing this only had to do with cosmetic reasons. I will definitively read your post Mr. Zorn and thank you for informing me about it. I was thinking about buying a new cap. However not from a pen show since we don't do any pen shows or anything pen related in Greece (unfortunately). Most likely from ebay.

      I have the Sailor Naginata and some fancy blade nibs coming after 2022 by a number of new workshop from China.  With all my respect, IMHO, they are all (bleep) in doing chinese characters.  Go use a bush, or at least a bush pen.

      It is the reason why I'm so keen on the idea of a personal library — of pens, nibs, inks, paper products, etc. — and spent so much money, as well as time and effort, to “build” it for myself (because I can't simply remember everything, especially as I'm getting older fast) and my wife, so that we can “know”; and, instead of just disposing of what displeased us, or even just not good enough to be “given the time of day” against competition from >500 other pens and >500 other inks for our at

      Agreed.  And I think it’s good to be aware of this early on and think about at the point of buying rather than rationalizing a purchase..

      Alas, one cannot know “good” without some idea of “bad” against which to contrast; and, as one of my former bosses (back when I was in my twenties) used to say, “on the scale of good to bad…”, it's a spectrum, not a dichotomy. Whereas subjectively acceptable (or tolerable) and unacceptable may well be a dichotomy to someone, and finding whether the threshold or cusp between them lies takes experiencing many degrees of less-than-ideal, especially if the decision is somehow influenced by factors o

      I got my first real fountain pen on my 60th birthday and many hundreds of pens later I’ve often thought of what I should’ve known in the beginning. I have many pens, the majority of which have some objectionable feature. If they are too delicate, or can’t be posted, or they are too precious to face losing , still they are users, but only in very limited environments..  I have a big disliking for pens that have the cap jump into the air and fly off. I object to Pens that dry out, or leave blobs o
