Flexmaster Pipe & Tube Joint, 1.25 Inch Pipe, Straight

Up to 4 degrees of angular misalignment per end is what these are built to absorb, so minor shifts in pipe alignment are well within range. The bulged, straight-through design is what makes that possible. One thing worth knowing up front, this joint seals the connection, but it's not meant to hold the hydraulic lines system together on its own. You'll still need your hangers, guides, and anchors in place to keep everything from shifting along the pipe.

Match-up looks right for size. This straight Flexmaster joint is meant for 1.25 inch pipe and calls out a 1.66 inch pipe outside diameter, with female compression ends on both sides.
