Loading...

Petes Plug®, T&P, Pressure & Temperature

Pete's Plugs allow you to take pressure and temperature readings quickly without leaving costly gauges on the line

Petes Plug II Cross Section

  • Quickly take a temperature or pressure reading
  • Self closing Neoprene or Nordel valves after probe removed
  • Cap to protect and additional seal
  • 1/8”, ¼”. & ½” NPT pipe connections
  • For 1/16” & 1/8” probes
  • Brass or Stainless-Steel housing

Neoprene Valve (blue strap) resists waxes, fats, oils, greases, petroleum products, and most refrigerants. Can be used for natural gas applications.

Nordel Valve (yellow strap) is an ethylene-propylene based synthetic rubber for hot and cold water, low steam, detergents, phosphate esters, ketone, alcohols, and glycols.
