I am looking for a fitting for the end of small diameter brass tubing.  It is a cylinder that has a cone on one end of it.  This fitting slides over the tubing and is soldered onto the tubing.  Then the cone would fit into another fitting that screws into a component of the car.  Do you have this in your inventory, or do you know where I might purchase the cone fitting and the fitting it fits into?  Sorry if I'm not very descriptive, I'm not an engineer.  Thanks
