Was curious as to the purpose or function of this white O-ringed shaped "spacer" that's found inside the 4001 bottle.

 

Is it suppose to be removed? Or is it supposed to be fitted snug into the black cap? Or just keep it at it is?

 

Any benefits or adverse effects to the ink if it's left on or removed?

 

Thanks FPN!

It is supposed to be fitted snug into the black cap.

Purpose is to secure better air tightness of the cap, but often this sealing layer gets stuck to the bottle opening, on the residues of the ink.

Lift it carefully and place back in the cap, fill your pen, wipe top of the bottle opening and cap the bottle.

Next time you open the bottle it should lift with the cap. In theory.

In practice - you may need to go through the same little procedure every (second) time you open the bottle...

 

This is nothing exclusive to Pelikan bottles...

Thanks MsRedPen Ill be sure to follow your instructions the next time I ink a pen.

 

I noticed that my Noodler bottles also have that white sealing layer, but without the donut hole in the middle.

In most cases that gasket is either glued in the cap, or just sits there. For some reason Pelikan chose something other: central pin through the gasket. The pin should however have a... thingy on it which is wider than the hole...

Hi, checked mine and the cap is made of some thermoplastic. The way the gasket is supposed to stay in place is via the center plug, the end of which is widened by heat and compression after the gasket has been installed.

Due to the fact that the gasket is made of a softer, more flexible material and the rim at the end of the plug is sometimes not properly formed (not wide enough) the gasket can sometimes stick to the mouth of the bottle. This can be due to residual ink between the gasket and mouth of the bottle and the lower air pressure inside that can form due to changes in temperature when the bottle was closed and when it is opened (i.e. if the bottle is closed when it is warmer and opened when it is colder).

 

Anyway, the previous factors are enough for the gasket to be pried off cap when you open the bottle.

I usually wipe both the gasket and the mouth of the bottle clean of ink after filling the pen to alleviate this problem. Doesn't help with changes in temperature though...

I hate when that happens to me. Usually due to ink left along the rim that dries and glues down that inner seal. I always have to remember to wipe the rim of the bottle when I'm done and, of course, I rarely do.

      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
