A 5/8" Stainless Ball Valve (Female x Male) for keg couplers or shanks.
This ball valve is incredibly handy for those wanting to control the shut off flow of liquid and gas lines on keg couplers or shanks that have a 5/8" thread. Highly recommended if you are disconnecting your coupler and not re-attaching to another keg immediately.
