Brass Pete's Plug® 1/4" MNPT x 1.5" Length with Neoprene Valve
Quickly measure system temperature and pressure without interrupting operation.
The Brass Pete's Plug® is designed to provide fast, repeatable access for pressure gauges and temperature probes in hydronic, HVAC, refrigeration, process piping, and industrial fluid systems. The self-sealing neoprene valve allows instruments to be inserted directly into the system while minimizing fluid loss, reducing maintenance time, and eliminating unnecessary shutdowns.
Manufactured from durable brass with a 1/4-inch MNPT connection, this 1.5-inch Pete's Plug® withstands operating pressures up to 1,000 PSI and is compatible with petroleum products, refrigerants, oils, greases, waxes, and many industrial fluids.
