They do make them, of course..
For the barbed end, you need to know the inside diameter of the hose. The hoses usually say on them.
If there is a threaded end needed...male or female and and size of the threaded fitting that it will engage.
You will also want to determine whether you want the spring-loaded, female end on the hose, or where you will attach the hose.
You could probably take the set-up to Nevada House of Hose and tell them what you want. They know it all, so you don't have to.
