Pipe Plug Immersion Heaters
Tubular
heaters or Mighty-Blade elements are brazed or welded in a
brass, steel or stainless steel pipe plug. Ratings from 350
watts to 38kw and numerous variations and options are
available. Pipe plug immersion heaters are generally used in
small to medium size containers at pressures up to 3000 psi
and are screwed directly through a threaded opening in the
tank wall.

Change T2 in catalog number to "T2R". 1" and 1-1/4" NPT items with
T2R Control are non-stock.
When maximum amperage is exceeded and external relay is required
(thermostat is used as pilot)Specify T1 thermostat and wire
thermostat to holding coil of relay.
