Pete’s Plug #710 Brass Pressure or Temperature PT Test Plug
The Pete’s Plug #710 is an industry-standard PT test plug designed for quick, accurate pressure and temperature readings in active hydronic and HVAC systems. Featuring a rugged brass body, a durable Nordel core, and 1/2″ NPT threads, this compact 1-1/2″ PT port eliminates the need for expensive permanent gauge installations. Technicians simply insert a needle adapter through the self-closing valves to take a reading, while the yellow Nordel retention strap ensures the protective cap is never lost.
