PepPen Fine Pen Needles – 31G × 8 mm
These fine pen needles feature a 31-gauge, 8 mm design and are supplied in a box of 100 sterile, single-use needles. Manufactured with precision grinding and multi-bevel sharpening, they are designed to support consistent, controlled operation when used with compatible pen systems.
Constructed using thin-wall technology, these needles allow for smooth flow characteristics while maintaining structural integrity. Each needle undergoes EO sterilization and is produced from non-toxic, non-pyrogenic materials.
Designed for universal pen compatibility, these needles are compatible with all PepPens sold here, as well as most standard pen-style systems.
