Question by: Kent H on Feb 10, 2026, 2:06 PM

Will this adapter let me hook up a 5/8-18 female fitting to a 5/8-11 male fitting? Just want to make sure I'm reading this right.

Yes, this threaded adapter allows you to connect a 5/8"-18 female fitting to a 5/8"-11 male fitting.

Question by: Bobby F on Nov 10, 2025, 7:30 AM

Does this adapter go from fine thread to coarse, or am I reading the specs backwards?

Answer by: Customer Support on Nov 11, 2025, 2:23 PM

You're reading it right. The female end is 5/8"-18, which is the fine thread, and the male end is 5/8"-11, which is the coarse thread. So it converts from fine to coarse as you move through the adapter. The overall length runs 2-1/4 inches, which gives you a little extra reach when you're working with SPX Power Team puller setups that need that thread transition.
