Male Jic X Male Metric W/Seal

On the JIC side, it has a 5/8 inch male with 7/8-14 UNF threads. The other end is a 20 mm metric male with M20 x 1.5 threads and it includes a seal on that metric side, so it’s meant to thread into an M20 x 1.5 female connection.

This adapter is constructed from durable steel, making it suitable for demanding industrial applications like hydraulic systems. Its robust design ensures it can withstand challenging conditions without compromising its core functionality.

That's the kind of situation this fits. One end threads into your M20 x 1.5 metric port and the other connects to your 5/8" JIC male line, so it bridges those two standards without any extra fittings in between. It's a straight configuration, steel construction, 44mm long with a 27mm hex width for wrenching. The metric side includes a seal, so you're not relying on thread alone to hold pressure at that connection.
