on saleNoodler's Nib Creaper Piston Seal O-Rings (2-Pack)

I just keep spending my money here. The service is excellent (that's one better than great), whoever picks up the phone knows how to answer your questions, shipping is speedy, products are top notch and packaged with a ridiculous amount of care, for which I am thankful.

I haven't needed these yet. I only purchased these because some reviewers stated that theirs were faulty, but Noodlers must have addressed the problem with the O-Rings before I purchased mine. I have two of their pens now and both have not needed these replacements.

I got these (and some silicon grease) because the arduous task of locating them in my own country was just not worth the hassle - just add a few to any order of Noodler's piston variants and you'll ensure you have the spares to maintenance your pen if ever it should require a new piston seal. (and since they're the right size, they can I think be used to seal some watches on the crown)Item was sent (in a much larger package including pens; I wouldn't just order these sent all the way around the world!) in a timely manner and was packed very well.

I have successfully used these o-rings to repair Vac-fill pens as well, Nathan has instructions on his u-tube channel. They work great! They also work to replace the point gaskets in Sheaffer snorkel pens!

I have not used these yet. I hav.e a couple of pens that I want to convert to eyedropper but have not gotten around to the conversion
