10cc luer lock oring syringe eccentric tip (eccentric tip means that the tip is set off to the side). Oring syringes are the perfect solution for hand feeding animals. Because of the unique oring plunger, the syringe works perfect when hand feeding and being able to use the same syringe repeatedly without sticking after a few uses. In most cases with proper cleaning these syringes will work for days and sometimes weeks. This slip tip syringe will hold a PetAg 2 oz. nipple, the Four Paws nipple and a cannula tip. Note: Always use caution when feeding animals with a nipple and syringe that the animal does not ingest the nipple. This could result in death.
