Fabricated and molded tank manufacturers are finding there is no longer a need for trips to a machine shop ause economical heavy-duty tank couplings, designed for their application, are now available. IPW tank couplings are easy to install and are sized to fit standard hole saw dimensions. They have a shoulder that gauges installation depth and provides for guaranteed square installations on flat surfaces. The shoulder also provides better weld strength and easy installation on round tanks. The shoulder and the low profile design, combined with thick cross sections, practically eliminate couplings shearing off from side impact. The thick cross-sections prevent the splitting commonly seen with FPT threaded couplings.
