Push-Fit Reducing Union 5/16"OD SS Coil x 3/8"OD Tubing
$6.15
This 5/16"OD SS Coil x 3/8"OD push-fit reducing union fitting is ideal for connecting hard metal tubing to hard plastic tubing. Or, if you would rather connect your 5/16"OD SS Coil to soft, flexible tubing, such as vinyl then you will need to purchase a stem to barb adapter for the ID of the tubing. For this push-fit reducing union you will need a 3/8"OD stem x 1/4", 5/16" or 3/8" barb adapter.
