End Caps & Tip Caps

Optimum® tip caps and end caps provide an airtight seal that allows you to prefill syringe barrels to save time or seal partially used syringes between shifts to reduce waste.

Tip caps have a large knurled grip that simplifies attachment, along with vents that prevent air from being introduced into the syringe barrel as the cap is installed.

End caps fit securely over syringe tabs and feature a center pushbutton that produces a snug, air-tight seal.

Follow these guidelines for safe operation.
