The QA1 1-1/2" OD tube adapter is a female chromoly fitting with right‑hand 5/8‑18 threads and a .250" wall. It combines a smooth outer diameter for finishing with a thick wall section for added robustness, offering consistent internal threads for secure coupling. CNC machined from chromoly to precise tolerances and available in QA1's range of sizes, it suits builds where higher wall thickness is required.
