Tubing Adapter Blueprint - 2.00" OD x 1.25" ID Tube, 1.125"-12 RH Thread Insert

This document is a simple dimensioned machining blueprint for a tubing adapter (T.A.) intended to be inserted into round steel tubing. A note at the top states the part is designed for 2.00-inch OD, 1.25-inch ID (0.375-inch wall) tubing. The side-view drawing shows a stepped cylindrical part with an overall length of 3.00 inches. The larger head/flange section is 2.00 inches in diameter and 0.750 inches long, stepping down (with a chamfered transition) to a 1.25-inch diameter shank that fits inside the tubing. The part has a through bore threaded 1.125 inches x 12 TPI with a right-hand pitch, and the wall thickness of the adapter at the shank is 0.125 inches. The material is specified as mild steel. A page marker "3/8" appears in the upper left corner, suggesting this is one sheet of a multi-page set (the album includes similar adapters for 1.375-inch and 1.5-inch ID tubing). A reader can use this drawing to machine or order a threaded tube insert/adapter, commonly used for fabricating adjustable suspension links or similar tubular components.
