Pumps are made of metal. They are not plated plastic that is going to break after a month or so. Yes, the part that sits in the liquid is ABS Plastic (you don't want metal sitting in liquid). Metal Soap Pumps - Stainless Soap Dispenser Pumps for your DIY Crafts. /// Purchase our reproduction zinc lids or our black lids and create your Mason Jar Soap Dispensers - or put together some Liquor Bottle Soap Dispensers Includes 2 pumps w/ 9" tubes and 2 white collar rings. With tube in the pump, it will reach down as far as 10-1/2" from the top of the bottle/jar that you use. Looking great in that Jack Daniels Liquor bottle. This measurement does not count the actual pump top. Just what goes inside bottle/jar. Tube can be easily cut to length with a pair of scissors to accommodate shorter bottles/jars. Jack Daniels Bottle / Colored Bottle / Mason jar not included. Pictured for visual reference only. Comes with 2 Pumps, 2 Tubes and 2 Collar Rings. Check your bottle size.... These are 28/400, but I know that many people do not know the size they need. I can tell you that these will screw directly onto a Jack Daniels Liquor Bottle and also a 2Liter Coke Bottle. Many bottles that you buy have different size necks. You can take the lid/pump from the bottle you would like the pump on and see if that lid/pump will fit onto the Jack bottle or a 2Liter Coke bottle. CHECK YOUR BOTTLE NECK SIZE: These will screw directly onto many liquor bottles, what you can do, is if you have a lid that will fit on the bottle you are wanting to use one on, try that lid on a 2Liter coke bottle.... these pumps will fit a 2Liter Coke bottle (and of course the Jack Daniels Bottle) and I know that they will fit the Jägermeister bottles as well. And for those bottles that they will not fit onto, these will also come with the Glue Down Collar Ring.
