Got a 1-inch tube on one end and a 1-1/4 inch tube on the other, is this the fitting that connects them two different sizes straight through?

Answer by: Customer Support on Dec 12, 2025, 6:36 AM

That's exactly what this one's built for. The A1 side handles the 1-inch tube OD with a 1-7/16-12 thread, and the A2 side steps up to the 1-1/4 inch tube OD on a 1-11/16-12 thread. Straight body, no bends, so it runs the connection inline without any change in direction.
