PT Plugs

PT plugs, also called test plugs, give quick access for checking pressure and temperature in HVAC and plumbing systems. Self-sealing valves let technicians insert probes without draining the system.

Features

  • Self-sealing cores – Neoprene and Nordel options
  • Brass and stainless bodies – suit service
  • Extended lengths – reach through insulation
  • Caps and retainers – protect cores

Choosing a PT Plug

Select core material for temperature and fluid, plus length for insulation thickness. Use test kits with matching probe sizes.

Centro supplies PT plugs and test kits.
