Luer-Lock O-Ring Syringes

These o-ring syringes are the best feeding syringes you can buy. Made in Denmark especially for animal care, they offer nonstick operation for better feeding control. Also available in slip-tip.

  • Washable and reusable again and again
  • Each syringe is sterile-packed and BPA-free
  • Black markings for easier reading
  • Non-toxic Ink
  • Fits our Silicone Mothering Nipples and Miracle Nipples


What's the difference between slip-tip and luer lock?

Slip-tip syringes have a long smooth tip.

  • Can be used with or without a nipple for feeding.
  • .5 ml, 1 ml, and 3 ml will fit all of our nipples except the Large Miracle Nipple.
  • 5 ml will not fit Miracle Nipples snugly, but will fit Silicone Mothering Nipples.
  • Available in .5 ml, 1 ml, 3 ml, and 5 ml sizes.

Luer-lock syringes have a short threaded barrel that will accept nipples and also screw-on needles (not sold here).

  • Must be used with a nipple for feeding.
  • Fits all of our nipples including the Large Miracle Nipple.
  • Available in 3, ml, 5 ml, 10 ml, and 20 ml sizes.
  • Fits all of our nipples including the Large Miracle Nipple.
Henry Recommends...

  • 3 ml - 5 ml for kittens and puppies - birth to 3 weeks

    Wildlife rehab to domestic

    Posted by Susan Andrews on 20th Aug 2019

    These are a must have for any Wildlife Rehabilitator. The O-ring allows for these to be reused many times, which is so cost effective for the smaller run rehabs to bigger facilities.

    Very smooth operation, never bind or stick like typical medical style syringes.
    Easy to clean. 5 Stars

    Luer-Lock Syringes

    These are awesome!!! Regular syringes stick after a few feedings. They work great with both nipples from Henry's.

    O-ring syringes

    I bought these to use with the miracle nipple. Unfortunately they are too short to attach to the nipple. I’m rehabbing a squirrel.

    A little disappointed

    Posted by Unknown on 18th Oct 2018

    I really liked the syringes to begin with and they worked really good but after only 3 or 4 uses the numbers and letters began coming off of them. Now they aren't very useful for measuring out formula. I have never had that happen with other brand syringes I have used in the past so not sure if I got a bad batch or that is common for this brand.

    Henry's Response: We're sorry about the numbers washing off. The manufacturer switched to non-toxic ink a couple of years ago, and it washes off very quickly. Try wrapping the barrel of the syringe with clear packing tape.

    Superior product!

    I had been using regular plunger syringes for months. I can’t tell you how much money I spend on all the syringes that went bad after a day or two of regular use. These are amazing! A little tape over the numbers and they last!

    Can't get much better than these!

    Posted by Lindsay on 2nd Aug 2018

    I have gotten O-ring syringes from other sites and these are the best. All others are hard to push or completely feeeze after a single use. These just keep working. The printing will eventually rub off, but packing tape solves all problems.
