Question by: Larry M on Aug 5, 2025, 6:20 PM

got a 4 inch line with a GJ male end on it, will this coupling hook up to that and then go into a boss port?

Answer by: Customer Support on Aug 7, 2025, 5:12 PM

Built with a GJ female thread on one side and a boss male on the other, it is meant to mate to a standard GJ style male counterpart and then thread into a boss style port connection commonly used on manifolds, cylinders, and valves.
