Silicone Grease

[dcwaites]

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!

Thanks!

I'll try this and post the results.

I'm also restoring a pen.

 

I'm thinking of using this http://www.ebay.com/itm/SEIKO-SILICON-GREASE-TSF-451-Waterproofing-Watch-Gaskets-4g-Japan-ePacket-/322188465062?hash=item4b03edd3a6:g:mAkAAOSwd0BVr6sD

 

Is it ok ?

"Diamant WetUndDry Silikon-Armaturen Fett Type 2" silicone grease (https://goo.gl/Ecwb8B) is safe to use in fountain pens.

 

Thank you for your help,

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....
