Question by: Keith M on Jun 29, 2025, 7:26 AM
Will this here adapter work to hook up two 9/16-18 JIC lines?
Answer by: Customer Support on Jul 1, 2025, 7:02 AM
Yes sir, it's purpose-built to connect two lines with that size and thread. The female end swivels, which makes it easier to tighten things down without twisting the hose.
