Pete's Plug

Pete's Plug is a patented, reusable test port for taking pressure and temperature readings from gas or liquid lines (like natural gas, hydronic systems) without shutting down the system, using a special needle probe that opens internal self-closing valves for a quick, leak-free measurement. Invented by Charles "Pete" Peterson Jr., this durable brass, or stainless-steel fittings replace bulky gauge cocks and thermometer wells, offering a convenient way for technicians to monitor system performance.
