Though it’s rare, sometimes an o-ring on one of our pens will come free or break. Now you can easily get a replacement for that missing or broken o-ring. We’re offering specific o-ring kits for all of our pens, with a link to a relatively inexpensive “tool” to help you install the o-ring.

This kit is for the Fountain K and Render K V2 (K Series) pens. The K Series pens feature a machined groove just past the internal cap threads that captures an 10mm x 1mm BUNA o-ring. These are made to spec for this project, though they are standard-size o-rings. Though we recommend silicone o-rings for most of our capped pens they tend to have a larger variance in cross-section width, and the K Series pens require a more precise size which BUNA has. This kit contains five (5) 10 x 1 BUNA o-rings in black.

We install these o-rings in our facility with the aid of THESE tools, by primarily using the flat of the pick or scraper and gently pressing the o-ring into the groove. It takes a few tries, but should pop in without using much force or the pointy ends of the tools.

Pricing is for 5 pieces.
