uxcell Nitrile Rubber O-Rings 8mm OD 6mm ID 1mm Width, Metric Sealing Gasket for Automotive Machine Plumbing, Pack of 50

For the fountain pen nerds: These bad boys, a little silicon grease and a Platinum Preppy? Ultra high capacity fountain pen that won't dry out. Works like a charm for that purpose.

Hard to find size. Perfect fit

They are dental o rings and I wanted them for that purpose.

Along with this, I bought another thing that can open up the valve. My gun was broken and it turns out it needed a new O-ring. The O ring was just a problem all along and plus these come in 50 pack and they are very cheap. hip hip hooray.

These fit my 13mm earrings/plugs great, but they are very thin. I was looking to add weight to my front-heavy earrings so these don’t quite meet my needs, but they’re great if you’re looking for o-rings that aren’t obvious.

I needed a small 1mm width, flexible drive belt. These were perfect. I ordered 3 ID sizes: 10mm ; 11mm; and 12mm. All 1mm width sizes of this O-ring to make sure I had a suitable fit. I needed a 1mm width and not sure of the inside / ID length. The OD did not concern me as long as the ID and Width would fit. The old one had stretched as it was used as a small drive belt on a device. I could not get an accurate measurement. Seem to be about 10mm -12mm between the 2 pulleys and the old belt was 1mm wide (round). I was not sure of the length required just the 1mm width. These O-rings worked fine as a drive belt for my device... No slipping as with the original. They should be fine for sealing fittings, etc. as they seem to be of uniform shape , well made and of good quality.

I bought these to use with my gushed earrings. Makes it much easier to switch out earrings.

Works perfectly with silicone grease on my platinum preppys to keep ink inside. 10/10 would recommend for artists using these these little fountain pens to draw with pigmented inks.
