I have a syringe that looks a lot like this. I'm not using it for medical purposes, but rather to create vacuum and pressure in hoses for testing out fuel delivery in small motors. When I look up syringes to buy it usually comes up with what are called "Luer taper", "Luer-Lok" and "Luer-Slip (registered trademarks), or generically "Luer-Lock" and "Luer-Slip". These look very different from the image posted above. If we take a look one example of a "Luer-Slip" syringe, they usually look like this:
The first problem being (for my purposes) that the syringe tip or opening is larger than I would like, and the second is that it's not tapered. I would ideally need both (tapered and smaller) to jam them into hoses/lines to get a decent seal.
Does anyone know what these type of syringes are called? I'm trying to search for them at different places.
The one I have and the one in the first image are curved, I don't know if they have a particular name, but I only need a straight one.
As another example, here are some sold on eBay:
The one on the left is close to what I'm looking for, but I would want a tapered tip beginning from a smaller size at the tip so I can slide it into a tube and get a good seal.
