How to Connect 12mm X 1mm Thread to 3/16 Vinyl Tubing
Coupling metric fasteners with SAE or standard American tubing requires a bit of thought and planning to complete the job without incurring any leaks in the coupler. When connecting a 12mm-by-1mm threaded coupler with 3/16-inch vinyl tubing, keep in mind that 3/16-inch tubing is 4.7625mm when converted to metric. This may help you when locating a coupler to connect the fastener to the hose. Does this Spark an idea?

Select a coupler with a 3/16-inch or 4.7625 mm barbed-hose coupler on one end and a 12mm-by-1mm threaded end. If the fastener you want to secure to the vinyl tubing has female threads, select a coupler with male threads. If the coupler you plan to use has male threads, select a coupler with female threads.
