Description
NovoPen 4 Adapters with O-Rings/Spacers — 5-Pack
This set contains five adapters and five matching O-rings/spacers, manufactured from PETG.
The NovoPen 4 was designed for Novo Nordisk Penfill insulin cartridges. Used with a modified NovoPen 4 cartridge holder, these adapters allow the pen to accept compatible standard 3 ml cartridges.
This is an improved, in-house refined version of the generic NovoPen adapter design available through online marketplaces. We have revised and retested the product through multiple in-house iterations before settling on this final version for market.
These adapters/O-rings are intended to be used with a modified cartridge holder. This is not included and can be performed with a sanding tool/dremel.

- 5 adapters
- 5 matching O-rings/spacers

Available in black or translucent blue. Colour is supplied at random, depending on stock availability; a specific colour cannot be guaranteed.
