Use d III {434) POWER July No worry about "weak links" when all piping is Crane The old saying "A chain is as strong as its weak est link" certainly applies to piping. But "weak links" needn't worry you when you standardise on Crane. For then you're assured the finest material for every part of the installation... valves, fittings, pipe and accessories. And that goes whether you're installing an air compressor or boiler, a simple washdown line or complex processing system. Whatever your piping needs, Crane can &1I the bill... In brass. Iron, steel or alloys. With this single source of supply you'll hod piping procedures are simplified and speeded. From design to purchasing to erection to main tenance . . . work' goes faster, smoother. And using Crane Quality in every part means uniform dependability in piping systems (tom end to end.
