Vintage Cherne Auto Test and Seal control panel, used by Cherne Industries, Inc. for testing and sealing sewer and drain pipelines, monitoring and controlling pipe testing equipment. Accurate and precise, the sealing ribs on Cherne's long test-ball plugs prevent any moisture or air from seeping across the barrier. This ensures that you get accurate results while inspecting or testing a pipe. It is designed for use in construction, waterworks, and plumbing industries to test pipe systems safely. The panel features gauges to monitor system pressure, end element pressure, and seal pressure. It includes manual controls and timers for inflation, testing, and curing processes. The system requires a 12V power supply to operate. Text, then call; no emails, cash only.
