Sterile disposable hypodermic needles are ultra sharp for consistent, trauma-free injections. Stainless steel needle with polypropylene hubs.
For use with Luer Lock or Luer Slip syringes.*
* Luer Lock twists on and Luer Slip slides on. All needles will work with either type of syringe.
Tried the 20g 1/2" needles on Jeffers 6 ml syringes for ivermectin plus, and they popped of the syringe as soon as I tried to inject. The hubs are way looser than the others I have ordered. I have a nearly full box I simply can't trust.
