The actual field parts are dia 1.5 steel tube. The team drawings call for 1.25 pipe. Steel tube is measured by outside diameter. Pipe is measured by outside diameter and wall thickness - called Schedule. 1.25 pipe has on OD of 1.66 - 0.160 over 1.50 so it isn't a match. Schedule 40 (the most common) has a wall thickness of 0.140 for an inside diameter of 1.38 Pipe is cheaper and more readily available (Home Despot) than steel tube. It can also be threaded and fittings are readily available for it.
