Stainless Steel Stop Plug is a type of plug designed to provide a secure connection for pipelines, valves, and other system components. Stainless steel provides superior strength, corrosion resistance, and durability compared to other materials such as brass or plastic. Det-Tronics offers M25 and 3/4 inch NPT stop plugs. When using any of the stop plugs, it is required that each plug be tightened to an installation torque of 35 ft-lb (47.5 N·m) and meet the minimum thread engagement requirements per the applicable standards in order to retain the IP66/IP67 rating.
