I would second the scuba dive shops. There seem to be a number of them in HK.

 

Silicone for diving has to be pure, otherwise you can end up poisoning yourself.

+1 on the silicone grease sold at SCUBA shops. I have a tiny tube, about half the length of my little finger, that is probably a lifetime suppy.

I use the food safe plumber's stuff for lubricating my pens. Not sure what other options there are for sealing the threads from ink seapage - I'm a safety convert :-)

Greetings to all you knowledgeable people on this fountain pen forum! :)

 

I have read a plethora of posts on silicone grease, still I can't decide if the silicone grease I bought is the right one for my cca. 88' Pelikan M800.

The silicone grease in question is "Diamant WetUndDry Silikon-Armaturen Fett Type 2" bought in a dive shop. The company page claims it is appropriate to use on O-rings (https://goo.gl/Ecwb8B). However, after googling the codes written beside - EPDM and NBR, I am not convinced anymore, if this is a '100% silicone' or a 'silicone based sealant'.

 

Does anyone know, based on the information in this post (this is all I have), if this silicone grease is safe to use in fountain pens?

 

Thank you for your effort,

MZ

I don't know anything about that particular type of silicone grease, but as a general rule, when in doubt, try on a cheap pen first, see how it works. You might even try it on something plastic that's not a pen, see if it hardens or if it remains greasy and tacky to the touch after a little while. I wouldn't put anything at all on a Pelikan unless I was 100% sure that it was safe. Sorry that's not very helpful, but good luck!

I would expect both Electronic (industrial) Silicone grease and car ignition Silicon grease would be pretty pure. In the car they go on rubber plug wires and withstand 15,000 volts or so. The rubber is preserved under the grease. I used to put a dab on the points (thank God for electronic ignitions). If I didn't get the dab of grease in the right spot I got to repeat the operation in a week or so. The insulator rubbing on the cam was bakelite.

 

In electronics there are all sorts of fun plastics insulators of many different materials. Can't use regular grease as it jellies many plastics over time. Thus silicone grease. Much safer to the future operation of switches, the usual location of electronics grease.

 

But the SCUBA dive shops are going to be the most fanatical for silicone grease purity, lives depend on it as pressurized air can start regular grease on fire and kill someone. Same with oxygen in someone's home or hospital. Although I am talking in order of more expensive....

      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
