Extremely bad combination of parts. The needle sits loosely in the bottle and does not seal the liquid in the bottle.The black cap through which the needle sits does not provide any compression fit to hold the needle in place or seal the cap to the needle. If you don't need the needle for your application, it might work for you, otherwise, it's useless. Unfortunately, a zero rating is available.....

Perfect size 18-gauge and 3" needle tip for oiling Teac reel to reel motor oiling port tubes.

Very handy. Lets you put oil exactly where it is needed.

In the future I may use these bottles for lubing some rifles, however I have found them most useful on the ) scale electric trains since some of assemblies needing oil is very tough to get to.

I have a habit of trying to keep special lubricants and penetrators at hand and some are expensive to me as in 8 fluid ounces for $24 as an example.The often (as in this case) the original fluid containers are able to dispense their product with the factory nozzle but in a “good for them” way.Lets take for example a Penetrator called Kroil. This fluid Starts to flow out lol open area as fast as possible when you turn it upside down to dispensed. The problem is is that it starts dispensing before you even get it near the area that requires the liquid.Now steps I am reviewing. I buy 2 ounce 4 ounce and 8 ounce bottles like this so that I can have marrying fluids and them and also keep a selection of different gauge needles and extended tubes to place the fluid where it should go.I remember working on a Lexus 460 where we had to loosen one particular area that just would not break and I told my friend that he was gonna have to buy me a bottle of Kroil By the time I flip the bottle upside down and try to aerial drop it where it’s supposed to go. I will have wasted at least a fourth of the bottle.Or 2 ounce squeezable container with the tube like tips. While I am holding the bottle upright, I can squeeze a certain amount of air out so that as soon as I start to go upside down to apply the liquid, I can take the pressure off the side of the bottle and it’s going to try to suck Air into the bottle instead of dropping liquid outParticular holding the liquid steel inside the bottle until it’s time for me to lightly depress the bottle tube release some of the fluid into the spot that is being worked onPretty much lubricated or penetrated my grass pretty well and more than likely, not even hit the spot that needed looseningBut the biggest bonus of all besides fluids, is the ability to add different size or links of needles or tubes for applicationOf my tubes 6 to 8 inches and now I am trying to experiment with the gauge of the tubes to get narrower version so that I can really dispense the fluid slowly but accuratelyThis is not a big deal for a lot of people in particular. I don’t have money to throw away. Something that could have dispensed instead of wastefully dispensed.I must admit I put buying these offer about four years and now I regret that because now I think about all the money I lost waiting but the other side of me order something I want to have all the fittings for it so I waited for me to have the funds to be able to get the different size bottles and different links of tubing I should say Gauge nozzles? I’m not sure what to call them but in the end, I got what I’ve been and I couldn’t be happier unless a lifetime supply of lubricants.I hope my suggestions might help you to save money in the future as well and think of different ways to use this product. It is very soft and flexible so you do not have to give it much pressure for the fluid to release which can be bad for people who are heavy-handed.I do not get any assistance with any of this, but Amazon does tell me if I get and if he will read my remarks so please give me a thumbs up if you found anything useful from this information. It’s not gonna hurt you just to push the button and it does help me in the end And makes me feel like knowledge is worth sharing to others.

You can do just about anything with these. My only suggestion is to glue the needle to the cap. The needle comes over pretty easy. Gorilla glue fixed this issue for me.

Got these to have smaller bottles of oil around the house.For the life of me, I can’t figure out how to get the needle part to stay in the bottle. It twists in, but doesn’t lock. I may have to superglue them on.In use however, this thing is like applying oil with a hypodermic syringe. Simply amazing.Recommend. I do wish they would make the nozzle lock into the bottle, however.

I repair musical instruments and as part of that I need to solder using a small torch, often in locations on the instrument that is difficult to reach with the liquid flux necessary for a proper solder joint. I have used other needle oilers where the needle is so fine that it deforms when close to heat -- finding these stainless needle oilers has solved that problem finally! The gauge of the needle portion is large enough that I can use it near the flame of the torch and it doesn't deform, and the length of these makes it easy to reach the solder into the cramped spaces I often have to work in. An excellent tool to have on hand for anybody who needs to get a liquid, whether it's oil, or soldering flux, or water or anything, into very tight spaces with precision.
