The FEDERAL PROCESS pb16 is a non-hardening, non-toxic pipe thread and gasket sealer supplied in a 1-pint brush-top can. It is formulated for sealing pipe joints, plugs, screwed fittings, and gasketed connections across a wide range of industrial and mechanical systems. Rated to 10000 psi for liquid service and 3000 psi for gas service, this gray compound sets within 24 hours and performs across a temperature range of -100 to 600 degrees F. It meets UL and CSA standards for both Canada and the US. Licensed plumbers, pipefitters, HVAC technicians, and refrigeration mechanics apply it wherever a reliable thread or gasket seal is required.
The pb16 is designed for use in steam systems, gas service lines, refineries, refrigeration systems, and chemical plants. Its compatibility with stainless steel, aluminum, Monel, plastics, and synthetic rubber makes it appropriate for a broad range of piping materials. The brush-top container allows direct application without additional tools, keeping the job clean and consistent on both threaded and gasketed connections.
Suitable for use on stainless steel, aluminum, Monel, plastics, and synthetic rubber pipe and fitting materials in steam systems, refineries, gas service lines, refrigeration systems, and chemical plant piping.
Applied by licensed plumbers, pipefitters, and HVAC or refrigeration technicians. Isolate and depressurize the line before disassembling any fitting or joint. Brush the compound evenly onto the male threads or gasket surface before assembly, following applicable codes such as the International Fuel Gas Code (IFGC) or International Plumbing Code (IPC) for your jurisdiction. Allow 24 hours of set time before returning the system to full pressure service.
