This quality reusable syringe from Mil-Comm has a rotating valve on/off system with an O-ring seal in the valve and dual O-rings on the plunger. The dispenser tip  tapers to a fine point allowing for precision placement into hard to reach places and/or spots that require deposition of small amounts of lubricant. This is the same syringe that comes standard in Mil-Comm's TW25B 0.5oz and MC2500 0.4oz  size formats.

This syringe is also ideal for lubricating your knives, multi-tools, survival, and rescue/EMT tools.
