John Wiley & Sons have the Audel series of books. We have Audel’s Pipefitter’s & Welder’s Pocket Manual in stock. This is one of the" been around a long time" books. Pipefitting books can stay around for so long because not many of the dimensions of pipe or pipe fittings change much over the years. (There are a few changes though such as the 3/4" BW. )
