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...

    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.

    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.

    These syringes are awesome! I ordered these because I acquired 2 orphaned baby squirrels. I ordered them with the miracle nipples which didn't work so well for the squirrels as the hole was a bit big and the milk came out too fast. May work better for bigger animals. I have other nipples I use and the fit on these syringes really well! These syringes are pretty much universal when it comes to fitting other nipples on them which is very helpful if you run into the issue I did.

    Luer-Lock syringes

    Posted by Sandy on 26th Sep 2017

    Great for feeding very young kittens. I was worried about them aspirating while feeding, they adapted to the nipple and the syringe

    Great Product

    The luer-lock style of syringe is my favorite. The nipple "locks" on so there is a less likely chance that a baby will swallow it.

    My dear husband came across a near-dead baby squirrel and had no idea how to care for it; thanks to the plethora of information here and the Miracle Syringe and Miracle Nipple, our little furry friend is now thriving.
