Question by: Tommy H on Mar 26, 2026, 7:23 AM

I'm just trying to make sure I'm getting the right size... that 5/8 inch tube OD, is that the outer diameter?

Answer by: Customer Support on Mar 28, 2026, 6:45 AM

That's correct. The 5/8 inch measurement refers to the outer diameter of the tube that this fitting is designed to connect.
